Check Windows install date / Howto find install time and date / Check how old is Windows

Sunday, October 22nd, 2017

how-to-find-windows-install-date-change-windows-install-date-change-file-folder-creation-date-howto

Just like us people operating systems have age, they have stages of young, teenage, grow up and old 🙂

Finding out how old is Windows as Operating System is important task for Windows system administrator and Tech support and can help you decide whether the OS requires a fresh reinstall as Windows is known historically to start misbehaving with its aging and especially for Computer Technicians / Support that have Windows Support clients or for Computer Clubs support guys, it is a among the good practices to re-install Windows every few years (every 3 / 4 years for servers to 7 years for Win Servers) and for Desktop or Gamers PCs the lifecycle of OS often much less, a reinstall is required every 2, 2.5 years or so.

Of course Desktop PC Windows users are much more prone to the requirement for frequent reinstalls, because they tend to install a lot of shit cracked, software games and a lot of ugly stuff, that infests the PC and fills up registry with a lot of broken and useless content.

Finding out, the install date of Programs (Applications) in Windows

 

1. In registry: HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionUninstall

InstallDate
YYYYMMDD (eg 20090301 for here March 1, 2009)


2. Through Control Panel -> Programs and Features

From Column:

"Installed on"


Determine the install date of Windows
 

1. In command line you have to issue:
 

systeminfo|find /i "original"

 


systeminfo-find-original-windows-server-screenshot-get-windows-install-date-howto

Note that this command will work on Windows Servers 2003, 2007, 2010 and Windows XP, 7, 8 but will show empty result on Windows 10

 

 

2. In cmd (command prompt):
 

WMIC OS GET installdate


systeminfo-find-original-windows-server-screenshot-get-windows-install-date-howto1

 

Reult you will get will be like:
20131019011658

Deciphered this Windows install date is on: 2013(year) 10(month) 19(date) 01(hour) 16(minutes) 58(seconds)
 

3. Another way to get the OS install date via Windows Registers:

 

HKLMSOFTWAREMicrosoftWindows NTCurrentVersionInstallDate

 

 

You will find  therea record number like 1414160971, to get the actual date you have to convert that to decimal
Конвертира се в decimal, и примерно излиза: 1414160971

To convert for those who have GNU / Linux or *BSD at hand the easiest way to convert it is to use below command that converts from unix timestampt to readable date command output:

 

 

echo 1414160971 | gawk '{print strftime("%c", $0)}'
24.10.2014 (fr) 17:29:31 EEST

 

For those that doesn't have GNU / Linux at hand you can use this online tool for conversion unix timestamp to readable output


How to edit creation date, and date of file or folder edit in Windows?

Как да се редактира дата на създаване, дата на редактиране на файл или папка под Windows:

Well why would you want to change the creation date of Windows install or creation date of file or folder edit in Windows?
Well just for the fun or because it can 🙂

Actually a lot of Windows white hats and mostly Script Kiddies (malicious crackers) do use this feature to falsify changed files in Windows lets say system files or any other Windows file, sometimes dumping the install date could be useful in computer data theft investigations or by crackers (please don't mix it with hackers, because term hacker is to be coined for a genius programmers and playful people).

It is possible to do a lot if not everything via Windows registry but perhaps the best way is to use a simple tool Attribute Changer, that is capable to change Windows file, folder and windows install creation date.

How to turn keyboard backlight on GNU / Linux, keyboard no backlight solution

Friday, October 20th, 2017

how-to-make-CM_Storm_Devastator-keyboard_backlight-work-on-linux-enabled-disable-keyboard-glowing-gnu-linux

If you're a GNU / Linux user and you happen to buy a backlighted keyboard, some nice new laptop whose keyboard supports the more and more modern keyboard growing or if you happen to install a GNU / Linux for a Gamer friend no matter the Linux distribution, you might encounter sometimes  problem even in major Linux distributions Debian / Ubuntu / Mint / Fedora with keyboard backlight not working.

Lets say you buy a Devastator II backlighted keyboard or any other modern keyboard you plug it into the Linux machine and there is no nice blinking light coming out of the keyboard, all the joy is gone yes I know. The free software coolness would have been even more grandiose if your keyboard was shiny and glowing in color / colors 🙂

But wait, there is hope for your joy to be made complete.

To make the keyboard backlight switch on Just issue commands:

 

xmodmap -e 'add mod3 = Screen_Lock'

 

# Turn on the keyboard bright lamps
xset led on

# Turns off the keyboard bright lamps
xset led off


If you want to make the keyboard backlight be enabled permanent the easiest solution is to

– add the 3 command lines to /etc/rc.local

E.g. to do so open /etc/rc.local and before exit 0 command just add the lines:

 

vim /etc/rc.local

 

xmodmap -e 'add mod3 = Screen_Lock'

# Turn on the keyboard bright lamps
xset led on

# Turns off the keyboard bright lamps
xset led off


If you prefer to have the keyboard colorful backlight enable and disabled from X environment on lets say GNOME , here is how to make yourself an icon that enabled and disables the colors.

That's handy because at day time it is a kind of meaningless for the keyboard to glow.

Here is the shell script:

#!/bin/bash
sleep 1
xset led 3
xmodmap -e 'add mod3 = Scroll_Lock'


I saved it as /home/hipo/scripts/backlight.sh

(don't forget to make it executable!, to do so run):

 

chmod +x /home/hipo/scripts/backlight.sh


Then create  the .desktop file at /etc/xdg/autostart/backlight.desktop so that it runs the new shell script, like so:

[Desktop Entry]
Type=Application
Name=Devastator Backlight
Exec=/home/hipo/scripts/backlight.sh
Icon=system-run
X-GNOME-Autostart-enabled=true

List of vulnerable wordpress plugins. Hacked, dangerous, vulnerable

Tuesday, October 17th, 2017

list-of-vulnerable-wordpress-pluginshacked-dangerous-vulnerable-wp

 

Have your wordpress has been hacked recently? Mine has Don't despair, below is a list of famous WordPress Plugins for its hackability.
Hope this helps you prevent your self on time and wipe out all the unnecessery plugins.
Double check the version number of Vulnerable plugins, and remove it only when you're sure its hackable. If you're sure you happen to run on your WordPress Blog or site one of the below plugins immediately deactivate and delete it.

 

Vulnerability types

A quick reminder of the most common security holes and issues WordPress plugins face. Please note that most problems are a combination of two or more types listed below.

Arbitrary file viewing
Instead of allowing only certain file source to be viewed (for example plugin templates) the lack of checks in the code allows the attacker to view the source of any file, including those with sensitive information such as wp-config.php

Arbitrary file upload
Lack of file type and content filtering allows for upload of arbitrary files that can contain executable code which, once run, can do pretty much anything on a site

Privilege escalation
Once the attacker has an account on the site, even if it’s only of the subscriber type, he can escalate his privileges to a higher level, including administrative ones.

SQL injection
By not escaping and filtering data that goes into SQL queries, malicious code can be injected into queries and data deleted, updated or inserted into the database. This is one of the most common vulnerabilities.

Remote code execution (RCE)
Instead of uploading and running malicious code, the attacker can run it from a remote location. The code can do anything, from hijacking the site to completely deleting it.

Block Web server over loading Bad Crawler Bots and Search Engine Spiders with .htaccess rules

Monday, September 18th, 2017

howto-block-webserver-overloading-bad-crawler-bots-spiders-with-htaccess-modrewrite-rules-file

In last post, I've talked about the problem of Search Index Crawler Robots aggressively crawling websites and how to stop them (the article is here) explaning how to raise delays between Bot URL requests to website and how to completely probhit some bots from crawling with robots.txt.

As explained in article the consequence of too many badly written or agressive behaviour Spider is the "server stoning" and therefore degraded Web Server performance as a cause or even a short time Denial of Service Attack, depending on how well was the initial Server Scaling done.

The bots we want to filter are not to be confused with the legitimate bots, that drives real traffic to your website, just for information

 The 10 Most Popular WebCrawlers Bots as of time of writting are:
 

1. GoogleBot (The Google Crawler bots, funnily bots become less active on Saturday and Sundays :))

2. BingBot (Bing.com Crawler bots)

3. SlurpBot (also famous as Yahoo! Slurp)

4. DuckDuckBot (The dutch search engine duckduckgo.com crawler bots)

5. Baiduspider (The Chineese most famous search engine used as a substitute of Google in China)

6. YandexBot (Russian Yandex Search engine crawler bots used in Russia as a substitute for Google )

7. Sogou Spider (leading Chineese Search Engine launched in 2004)

8. Exabot (A French Search Engine, launched in 2000, crawler for ExaLead Search Engine)

9. FaceBot (Facebook External hit, this crawler is crawling a certain webpage only once the user shares or paste link with video, music, blog whatever  in chat to another user)

10. Alexa Crawler (la_archiver is a web crawler for Amazon's Alexa Internet Rankings, Alexa is a great site to evaluate the approximate page popularity on the internet, Alexa SiteInfo page has historically been the Swift Army knife for anyone wanting to quickly evaluate a webpage approx. ranking while compared to other pages)

Above legitimate bots are known to follow most if not all of W3C – World Wide Web Consorium (W3.Org) standards and therefore, they respect the content commands for allowance or restrictions on a single site as given from robots.txt but unfortunately many of the so called Bad-Bots or Mirroring scripts that are burning your Web Server CPU and Memory mentioned in previous article are either not following /robots.txt prescriptions completely or partially.

Hence with the robots.txt unrespective bots, the case the only way to get rid of most of the webspiders that are just loading your bandwidth and server hardware is to filter / block them is by using Apache's mod_rewrite through

 

.htaccess


file

Create if not existing in the DocumentRoot of your website .htaccess file with whatever text editor, or create it your windows / mac os desktop and transfer via FTP / SecureFTP to server.

I prefer to do it directly on server with vim (text editor)

 

 

vim /var/www/sites/your-domain.com/.htaccess

Above rules are Bad bots prohibition rules have RewriteEngine On directive included however for many websites this directive is enabled directly into VirtualHost section for domain/s, if that is your case you might also remove RewriteEngine on from .htaccess and still the prohibition rules of bad bots should continue to work
Above rules are also perfectly suitable wordpress based websites / blogs in case you need to filter out obstructive spiders even though the rules would work on any website domain with mod_rewrite enabled.

Once you have implemented above rules, you will not need to restart Apache, as .htaccess will be read dynamically by each client request to Webserver

2. Testing .htaccess Bad Bots Filtering Works as Expected


In order to test the new Bad Bot filtering configuration is working properly, you have a manual and more complicated way with lynx (text browser), assuming you have shell access to a Linux / BSD / *Nix computer, or you have your own *NIX server / desktop computer running
 

Here is how:
 

 

lynx -useragent="Mozilla/5.0 (compatible; MegaIndex.ru/2.0; +http://megaindex.com/crawler)" -head -dump http://www.your-website-filtering-bad-bots.com/

 

 

Note that lynx will provide a warning such as:

Warning: User-Agent string does not contain "Lynx" or "L_y_n_x"!

Just ignore it and press enter to continue.

Two other use cases with lynx, that I historically used heavily is to pretent with Lynx, you're GoogleBot in order to see how does Google actually see your website?
 

  • Pretend with Lynx You're GoogleBot

 

lynx -useragent="Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" -head -dump http://www.your-domain.com/

 

 

  • How to Pretend with Lynx Browser You are GoogleBot-Mobile

 

lynx -useragent="Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8B117 Safari/6531.22.7 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)" -head -dump http://www.your-domain.com/

 


Or for the lazy ones that doesn't have Linux / *Nix at disposal you can use WannaBrowser website

Wannabrowseris a web based browser emulator which gives you the ability to change the User-Agent on each website req1uest, so just set your UserAgent to any bot browser that we just filtered for example set User-Agent to CheeseBot

The .htaccess rule earier added once detecting your browser client is coming in with the prohibit browser agent will immediately filter out and you'll be unable to access the website with a message like:
 

HTTP/1.1 403 Forbidden

 

Just as I've talked a lot about Index Bots, I think it is worthy to also mention three great websites that can give you a lot of Up to Date information on exact Spiders returned user-agent, common known Bot traits as well as a a current updated list with the Bad Bots etc.

Bot and Browser Resources information user-agents, bad-bots and odd Crawlers and Bots specifics

1. botreports.com
2. user-agents.org
3. useragentapi.com

 

An updated list with robots user-agents (crawler-user-agents) is also available in github here regularly updated by Caia Almeido

There are also a third party plugin (modules) available for Website Platforms like WordPress / Joomla / Typo3 etc.

Besides the listed on these websites as well as the known Bad and Good Bots, there are perhaps a hundred of others that might end up crawling your webdsite that might or might not need  to be filtered, therefore before proceeding with any filtering steps, it is generally a good idea to monitor your  HTTPD access.log / error.log, as if you happen to somehow mistakenly filter the wrong bot this might be a reason for Website Indexing Problems.

Hope this article give you some valueable information. Enjoy ! 🙂

How to configure mutual Apache WebServer SSL authentication – Two Way SSL mutual authentication for better security and stronger encryption

Tuesday, September 12th, 2017

how-to-configure-one-way-and-two-way-handshake-authentication-apache-one-and-two-way-ssl-handshake-authentication-explained-diagram

In this post I'm about to explain how to configure Apache Web server for Two Way SSL Authentication alone and how to configure Two Way SSL Authentication for a Certain Domain URL Locations and the mixture of both One Way standar SSL authentication and Two Way Handshake Authentication .
 

Generally before starting I have to say most Web sites does not require a Mutual SSL  Authentication (the so called Two-Way SSL).

In most configurations Apache Web server is configured for One Way Basic authentication where The Web server authenticates to the Client usuall that's Browser program such as Mozilla  Firefox / Chrome / IE / Epiphany whatever presenting certificate signed by Trustable Certificate Authority such as VeriSign.

1WaySSL-clien-to-server-illustrated
 

The authority then autneticates to the browser that the Installed certificate on the Apache Web Server is trustable and the website is not a fraudulant, that is especially important for websites where sensitive data is being transferred, lets say Banks (Doing Money Transfers online), Hospitals (Transfelling your Medical results data) or purchasing something from Amazon.com, Ebay.Com, PayPal etc.

Once client validates the certificate the communication line gets encrypted based on Public Key, below diagram illustrates this.

Public Ke Cryptography diagram how it works

However in some casis where an additional Security Hardening is required, the Web Server might be configured to require additional certificate so the authentication between Client -> Server doesn't work by certificating with just a Server provided certificate but to work Two Ways, e.g. the Client might be setup to also have a Trusted Authority Certificate and to present it to server and send back this certificate to the Server as well for a mutual authentication and only once the certificate handshake between;

client -> server and server -> client

2WaySSL-client-to-server-and-server-to-client-mutual-authentication-illustration

is confirmed as successful the two could establish a trustable encypted SSL channel over which they can talk securely this is called
Two way SSL Authentication.

 

1. Configure Two Way SSL Authentication on Apache HTTPD
 

To be able to configure Two Way SSL Authentication handshake on Apache HTTPD just like with One way standard one, the mod_ssl Apache module have to enabled.

Enabling two-way SSL is usually not done on normal clients but is done with another server acting as client that is using some kind of REST API to connect to the server

 

The Apache directive used for Mutual Authentication is SSLVerifyClient directive (this is provided by mod_ssl)

the options that SSLVerifyClient receives are:

none: instructs no client Certificate is required
optional: the client is allowed to present a valid certificate but optionally
require: the client is always required to present a valid Certificate for mutual Authenticaton
optional_no_ca: the client is asked to present a valid Certificate however it has to be successfully verified.

In most of Apache configuratoins the 2 ones that are used are either none or require
because optional is reported to not behave properly with some of the web browsers and
optional_no_ca is not restrictive and is usually used just for establishing basic SSL test pages.

At some cases when configuring Apache HTTPD it is required to have a mixture of both One Way and Two Way Authentication, if that is your case the SSLVerifyClient none is to be used inside the virtual host configuration and then include SSLVerifyClient require to each directory (URL) location that requires a client certificate with mutual auth.

Below is an example VirtualHost configuration as a sample:

 

The SSLVerifyClient directive from mod_ssl dictates whether a client certificate is required for a given location:
 

<VirtualHost *:443>

SSLVerifyClient none
<Location /whatever_extra_secured_location/dir>
            …
            SSLVerifyClient require
</Location>
</VirtualHost>

 

Because earlier in configuration the SSLVerifyClient none is provided, the client will not be doing a Two Way Mutual Authentication for the whole domain but just the selected Location the client certificate will be not requested by the server for a 2 way mutual auth, but only when the client requests the Location setupped resouce a renegotiation will be done and client will be asked to provide certificate for the two way handshake authentication.

Keep in mind that on a busy servers with multitudes of connections this renegotiation might put an extra load on the server and this even can turn into server scaling issue on a high latency networks, because of the multiple client connects. Every new SSL renegotiation is about to assign new session ID and that could have a negative impact on overall performance and could eat you a lot of server memory.
To avoid this often it i suseful to use SSLRenegBufferSize directive which by default is set in Apache 2.2.X to 128 Kilobytes and for multiple connects it might be wise to raise this.

A mutual authentication that is done on a Public Server that is connected to the Internet without any DMZ might be quite dangerous thing as due to to the multiple renegotiations the server might end up easily a victim of Denial of Service (DOS) attack, by multiple connects to the server trying to consume all its memory …
Of course the security is not dependent on how you have done the initial solution design but also on how the Client software that is doing the mutual authentication is written to make the connections to the Web Server.

 

2. Configure a Mixture of One Way Standard (Basic) SSL Authentication together with Two Way Client Server Handshake SSL Authentication
 


Below example configuring is instructing Apache Webserver to listen for a mixture of One Way standard Client to browser authentication and once the client browser establishes the session it asks for renegotiation for every location under Main Root / to be be authenticated with a Mutual Two Way Handshake Authentication, then the received connection is proxied by the Reverse Proxy to the end host which is another proxy server listening on the same host on (127.0.0.1 or localhost) on port 8080.

 

<VirtualHost *:8001>
  ServerAdmin name@your-server.com
  SSLEngine on
  SSLCertificateFile /etc/ssl/server-cert.pem
  SSLCertificateKeyFile /etc/ssl/private/server-key.pem

  SSLVerifyClient require
  SSLVerifyDepth 10
  SSLCACertificateFile /home/etc/ssl/cacert.pem
  <location />
    Order allow,deny
    allow from all
    SSLRequire (%{SSL_CLIENT_S_DN_CN} eq "clientcn")
 </location>
  ProxyPass / http://127.0.0.1:8080/
  ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>

 

 

3. So what other useful options do we have?
 


Keep Connections Alive

This is a good option but it may consume significant amount of memory. If Apache is using the prefork MPM (as many Webservers still do instead of Apache Threading), keeping all connections alive means multiple live processes. For example, if Apache has to support 1000 concurrent connections, each process consuming 2.7MB, an additional 2700MB should be considered. This may be of lesser significance when using other MPMs. This option will mitigate the problem but will still require SSL renegotiation when the SSL sessions will time out.

Another better approach in terms of security to the mixture of requirement for both One Side Basic SSL Authentication to a Webserver and Mutual Handshake SSL Auth is just to set different Virtualhosts one or more configuration to serve the One Way SSL authentication and others that are configured just to do the Mutual Two Way Handshake SSL to specified Locations.

4. So what if you need to set-up multiple Virtualhosts with SSL authentication on the Same IP address Apache (SNI) ?

 

For those who did not hear still since some time Apache Web Server has been rewritten to support SNI (Server Name Indication), SNI is really great feature as it can give to the webserver the ability to serve multiple one and two way handshake authentications on the same IP address. For those older people you might remember earlier before SNI was introduced, in order to support a VirtualHost with SSL encryption authentication the administrator had to configure a separate IP address for each SSL certificate on each different domian name.  

SNI feature can also be used here with both One Way standard Apache SSL auth or Two Way one the only downside of course is SNI could be a performance bottleneck if improperly scaled. Besides that some older browsers are not supporting SNI at all, so possibly for public services SNI is less recommended but it is better to keep-up to the good old way to have a separate IP address for each :443 set upped VirtualHost.
One more note to make here is SNI works by checking the Host Header send by the Client (browser) request
SSL with Virtual Hosts Using SNI.

SNI (Server Name Indication) is a cool feature. Basically it allows multiple virtual hosts with different configurations to listen to the same port. Each virtual host should specify a unique server name identification using the SeverName directive. When accepting connections, Apache will select a virtual host based on the host header that is part of the request (must be set on both HTTP and SSL levels). You can also set one of the virtual hosts as a default to serve clients that don’t support SNI. You should bear in mind that SNI has different support levels in Java. Java 1.7 was the first version to support SNI and therefore it should be a minimum requirement for Java clients.

5. Overall list of useful Options for Mutual Two Way And Basic SSL authentication
 

Once again the few SSL options for Apache Mutual Handhake Authentication

SSLVerifyClient -> to enable the two-way SSL authentication

SSLVerifyDepth -> to specify the depth of the check if the certificate has an approved CA

SSLCACertificateFile -> the public key that will be used to decrypt the data recieved

SSLRequire -> Allows only requests that satisfy the expression


Below is another real time example for a VirtualHost Apache configuration configured for a Two Way Handshake Mutual Authentication


For the standard One way Authentication you need the following Apache directives

 

SSLEngine on -> to enable the single way SSL authentication

SSLCertificateFile -> to specify the public certificate that the WebServer will show to the users

SSLCertificateKeyFIle -> to specify the private key that will be used to encrypt the data sent
 


6. Configuring Mutual Handshake SSL Authentication on Apache 2.4.x

Below guide is focusing on Apache HTTPD 2.2.x nomatter that it can easily be adopted to work on Apache HTTPD 2.4.x branch, if you're planning to do a 2 way handshake auth on 2.4.x I recommend you check SSL / TLS Apache 2.4.x Strong Encryption howto official Apache documentation page.

In meantime here is one working configuration for SSL Mutual Auth handshake for Apache 2.4.x:

 

<Directory /some-directory/location/html>
    RedirectMatch permanent ^/$ /auth/login.php
    Options -Indexes +FollowSymLinks

    # Anything which matches a Require rule will let us in

    # Make server ask for client certificate, but not insist on it
    SSLVerifyClient optional
    SSLVerifyDepth  2
    SSLOptions      +FakeBasicAuth +StrictRequire

    # Client with appropriate client certificate is OK
    <RequireAll>
        Require ssl-verify-client
        Require expr %{SSL_CLIENT_I_DN_O} eq "Company_O"
    </RequireAll>

    # Set up basic (username/password) authentication
    AuthType Basic
    AuthName "Password credentials"
    AuthBasicProvider file
    AuthUserFile /etc/apache2/htaccess/my.passwd

    # User which is acceptable to basic authentication is OK
    Require valid-user

    # Access from these addresses is OK
    Require ip 10.20.0.0/255.255.0.0
    Require ip 10.144.100
</Directory>

Finally to make the new configurations working depending you need to restart Apache Webserver depending on your GNU / Linux / BSD or Windows distro use the respective script to do it.

Find all running hosts, used IPs and ports on your local wireless / ethernet network or how to do a basic network security audit with nmap

Monday, September 4th, 2017

Find all running hosts / used IPs on your local wireless or ethernet network

nmap-scn-local-network-find-all-running-hosts-used-IPs-on-your-wireless-ethernet-network

If you're using a Free Software OS such as GNU / Linux or some other proprietary OS such as Mac OS X or Windows and you need a quick way to check all running IPs hosts / nodes locally on your current connected Ethernet or Wireless network, here is how to do it with nmap (Network exploration and security tool port scanner).

So why would you do scan that? 

Well just for fun, out of curiousity or just because you want to inspect your local network whether someone unexpected cracker did not break and is not using your Wi-Fi or Ethernet local network and badly snoring your network listening for passwords.

Before you start you should have installed NMAP network scanner on your GNU / Linux, to do so on 

Redhat Based Linux (Fedora / CentOS / Redhat Enterprise RHEL):

 

yum -y install nmap

 

On Deb based GNU / Linux-es such as Ubuntu / Mint / Debian etc.

 

apt-get install –yes nmap

 

To install nmap on FreeBSD / NetBSD / OpenBSD OS issue from console or terminal:

 

cd /usr/ports/security/nmap
make install clean 

 

or if you prefer to install it from latest binary instead of compiling

 

pkg_add -vr nmap

 

On a proprietary Mac OS X (I don't recommend you to use this obnoxious OS which is designed as a proprpietary software to steal your freedom and control you, but anyways for Mac OS victims), you can do it to with Macs equivalent tool of apt-get / yum called homebrew:

Open Mac OS X terminal and to install homebrew run:

 

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install nmap
brew search nmap
brew info nmap

 

If you want to do it system wide become root (super user) from Mac terminal with

 

su root

 

and run above commands as administrator user.

Windows users might take a look at Nmap for Windows or use the M$ Windows native portqry command line port scanner

Test whether nmap is properly installed and ready to use with command:

SEE THE MAN PAGE (http://nmap.org/book/man.html) FOR MORE OPTIONS AND EXAMPLES

 


Most local router local networks are running under an IP range of 192.168.0.1/24 (192.168.0.1.254) or 192.168.1.1/24 or at some weird occasions depending on how the router is configured it might be something like 192.168.10.0/24 to be sure on what kind of network your computer is configured, you can check with ifconfig command, what kind of network IP has the router assigned to your computer, here is output from my Debian GNU / Linux /sbin/ifconfig

          RX bytes:141318655 (134.7 MiB)  TX bytes:7391330 (7.0 MiB)

 

As evident from above output my router assigns IPs via DHCP once authenticated into the Wi-Fi router under standard IP range of 192.168.0.0/24

So under this IP range case, to inspect my small local networkconnected computer I had to run from gnome-terminal or under a /dev/ttyX virtual console:

 

hipo@noah:~$ nmap -sn 192.168.0.0/24

Starting Nmap 6.00 ( http://nmap.org ) at 2017-09-04 12:45 EEST
Nmap scan report for pcfreak (192.168.0.1)
Host is up (0.011s latency).
Nmap scan report for 192.168.0.103
Host is up (0.00011s latency).
Nmap done: 256 IP addresses (2 hosts up) scanned in 2.53 seconds


-sn argument instructs nmap to do the so called ping scan, e.g. not to do a port s
can after host discovery but just print available hosts that are responding

Some bigger corporate networks are configured to run a couple of local networks simultaneously such as 192.168.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24 etc.

So if that's the case you can add more virtual IPs to your ifconfig after becoming root super user with:

 

hipo@noah:~$ su root 
Password: 
root@noah:/home/hipo# 

 

And then run:

 

/sbin/ifconfig wlan0:0 192.168.1.110 netmask 255.255.255.0
/sbin/ifconfig wlan0:1 192.168.2.110 netmask 255.255.255.0

 

etc.

Note that here I purposefully choose .110 IP because often the 192.168.1.1 is an IP assigned to the router and that might cause some IP conflicts and trigger alarms in the router security which I want to avoid.

To check just added extra Virtual IPs on wlan0 wireless interface (note that depending on your Wi-Fi card and your driver this interface might come under a different name on your computer):

 

root@noah# /sbin/ifconfig |grep -i wlan0 -A 1
wlan0     Link encap:Ethernet  HWaddr 00:1c:bf:bd:25:59  
          inet addr:192.168.0.103  Bcast:192.168.0.255  Mask:255.255.255.0

wlan0:0   Link encap:Ethernet  HWaddr 00:1c:bf:bd:25:59  
          inet addr:192.168.1.110  Bcast:192.168.1.255  Mask:255.255.255.0

wlan0:1   Link encap:Ethernet  HWaddr 00:1c:bf:bd:27:59  
          inet addr:192.168.2.110  Bcast:192.168.2.255  Mask:255.255.255.0

 

 

If you're scanning not on your own network but on a public connected network you might prefer to not use the ping scan as this might identify you in router's firewall as possible intruder and could cause you headaches, besides that some network connected nodes are connected to not respond on a ping scan (some networks purposefully disable pings at all) to avoid possibility of the so called ping flood that might overload a router buffer or bring down hosts on the network beinf flooded.

If you have doubts that a network has ping disabled and it shows no result you can give a try to the so called SYN / FIN Stealth packet scan with added requirement to scan for UDP open ports (-sS) argument

 

root@noah:/~# nmap -sS -sU -sT 192.168.0.1-255

Starting Nmap 6.00 ( http://nmap.org ) at 2017-09-04 13:31 EEST
Nmap scan report for pcfreak (192.168.0.1)
Host is up (0.012s latency).

Nmap scan report for 192.168.0.103
Host is up (0.000012s latency).
Not shown: 999 closed ports
PORT   STATE SERVICE
22/tcp open  ssh


You might also like to add some verbosy (that would generate a lot of output so be careful):

In case if above scan fails due to firewalls and you have a ping scan disabled on the network too you might also try out the so called nmap connect TCP connect scan (-sT), that would avoid the SYN scan. The -sT is useful also if you're not possessing root superprivileges on nmap running host.

 

nmap -sS -sU 192.168.0.1-255


Note that connect scan could take ages as nmap tries to connect every port from default port scanned ranged on remote found hosts that are reporting as up and running.

If the shown results lead you find some unknown computer / tablet / mobile / phone device connected to your network, then connect to your router and thoroughfully inspect the traffic flowing through it, if you find intruder cut him off and change immediately your router passwords and monitor your network periodically to make sure the unwanted guest did not go back in future.

There is much more you can do with nmap so if you have some extra time and interest into penetration testing I recommend you check out Nmap Book (The Official Nmap project guide to Network Discovery and Security Scanning)

Upgrade old crappy Windows 7 32 bit to Windows 10 32 bit, post install fixes and impressions / How to enter Safe Mode in Windows 10

Wednesday, June 28th, 2017

Upgrade-Windows-7-Vista-XP-to-Windows-10-upgrade-howto-observations-post-fixes

However as I've been upgrading my sister's computer previously running Windows 7 to Windows 10 (the process of upgrading is really simple you just download Windows-Media-Creation-tool from Microsoft website and the rest comes to few clicks (Accept Windows 10 User Agreement, Create current install  restore point (backup) etc.) and waiting some 30 minutes or so for the upgrade to complete.

windows-7-to-10-windows-setup-upgrade-this-pc-prompt

Then it was up to downloading some other updates on a few times and restarting the computer, each time the upgrades were made and all the computer was ready. I've installed Avira (AntiVirus) as I usually do on new PCs and downloaded a bunch of anti-malware (MalwareBytes / Rfkill  / Zemanta)  to make sure that the old upgraded  WIndows was not already infected before the upgrade and I've found a bunch of malware, that got quickly cleared up.

Anyways I've tried also another tool called ReimagePlus – Online Computer Repair in order to check whether there are no some broken WIndows system files after the upgrade

Reimage_Repair-Windows-fix-windows-failing-services-and-broken-windows-installations-clear-up-malware
(here I have to say I've done that besides running in an Administrator command prompt (cmd.exe) and running
 

sfc /scannow


command to check base system files integrity, which luckily showed no problems with the Win base system files.

ReimagePlus however showed some failed services and some failed programs that were previously installed from Windows 7 before the upgrade and even it showed indication for Trojan present on computer but since ReImagePlus is a payed software and I didn't have the money to spend on it, I just proceeded to clean up what was found manually.

After that the computer ran fine, with the only strange thing that some data was from hard drive was red a bit too frequently, after a short call with a close friend (Nomen) – thx man, he suggested that the frequenty hdd usage might be related to Windows Search Indexing service database rebuilt and he adviced me to disable it which I did following this article How to speed up Windows by disabling Search Index Service.

One issue worthy to mention  stumbled upon after the upgrade was problems with Windows Explorer which was frequently crashing and "restarting the Desktop", but once, I've enabled all upgrades from Microsoft and Applied them after some update failures and restarts, once all was up2date to all latest from Microsoft, Explorer started working normally.

In the mean time while Windows Explorer was crashing in order to browse my file system I used the good old Win Total Command or Norton Commander for Windows – WinNC (with its most cool bizzarre own File Explorer tool).

Windows-Total-commander-tool-running-on-MS-Windows-10

As I wanted to run a MalwareBytes scan and Antivirus under Windows Safe-Mode, I tried entering it by restarting the Computer and pressing F8 a number of times before the Windows boot screen but this didn't work as Safe-Mode boot was changed in Windows 10 to be callable in another way because of some extra Windows Boot speed up optimizations, in short the easiest way I found to enter Windows 10 Safe Mode was to Hit Start Button -> Choose Restart PC and keep pressed SHIFT button simultaneously
that calls a menu that gives you some restore options, along with safe mode options for those who want to read more on How to Enter Safe mode (Command Prompt) on Windows 10 – please read this article.

Windows-10-enable-Safe-Mode-options-screen

Once the upgrade was over and all below done unfortunately I've realized her previously installed WIndows 7 is x86 (32 bit) version and the Acer notebook 5736Z where it is being installed is actually X64 (64 bit), hence I've decided to upgrade my dear sis computer to a 64 Bit Windows 10 and researched online whether, there is some tool that is capable to upgrade WIndows 10 from 32 bit to Windows 10 64 bit just to find out the only option is to either use some program to creaty a backup of files on the PC or to manually copy files to external hard drive and reinstall with a Windows 10 64 bit bootable USB Flash or CD / DVD image, so I took my USB flash and used again Windows Media Creation Tool to burn Windows and re-install with the 64 bit iso.

If you're wonder about why I choose to re-install finally Win 10 32 bit with Win 64 bit, because you might think performance difference might be not really so dramatic, then I have to say the Acer notebook is equipped with 4 Gigabytes of RAM Memory and Windows 10 32bit  (Pro) could recognize a maximum of 3 Gigabytes (2.9 GB if I have to be precise) and 1 Gigabyte of memory stays totally unusued all the time with  Winblows 10 32 bit.

Windows-10-4gb-memory-present-only-3gb-usable-why-reason-and-solution

I've tried my best actually to not loose time to fully upgrade Windows 7 (32 bit) -> Windows 10 (64 bit) but to make Windows 7 32 bit Windows to use more than the default Limitation of 3GB of memory by using this thirt party PAE Externsion Kernel Patch
which is patching the Windows Kernel to extend the Windows support for PCs with up to 128 GB of memory however it turned out that this Patch file is not compatible with my Windows Kernel version once I followed readme instructions.

It seems the PAE (Physical Address Extension) is supported by default  by Microsoft only on 32 bit Windows Server 10 to read more on the PAE if interested give a look here.

Well that's all folks, the rest I did was to just boot from the USB drive just burned and re-install WIndows and copy my files from User profile / Downloads / Pictures / Music etc. to the same locations on the new installed Windows 10 professional 64 bit and enjoy the better performance.

Howto to Unlock Mtel locked Mobile Phone ZTE Blade 3 IMEI 866643012872768 to connect to Telenor and Vivacom mobile networks in Bulgaria

How to unlock Unlock Mtel locked Mobile Phone ZTE Blade 3 IMEI 866643012872768


Thanks to this little forum after a very thoroughful research on the topic howto unlock my ZTE Blade 3
in Russian Google.ru / United Stated Google.US and UK Google.Co.Uk I've figured out a number of ways recommended

I've lost some time watching also few videos illustrating howto unlock the phone for other non MTEL mobile operators with

some third party cracker software  which seemed like a good way to infect your PC with spyware for example
videos:
Direct Unlock ZTE BLADE 3 & ZTE RACER 3 – YouTube
Unlock ZTE Blade 3, Blade V & Blade Q Mini – YouTube

there are a number of ways and paid software that could do various non-conventional things like unlock the phone for example:
GB Key

gbstream-gbkey-fast-unlocker-zte-blackberry-huawei-apple-motorola-alcatel-lg-unlock

Here is description of GB Key

You can Call it UNLIMITED – Direct Unlocker, Code Calculator, Code Reader, is fast, easy to use, encrypted, more than 200 models supported and most of it is it's UNLIMITED use. Updates come on regular basis with addition to new models and features.

Supported Models

More than 500 supported models from mobile phones to modems and growing.

Currently supports around 260 MEPs & more than 9500 PRDs (and growing..) .

FREE & UNLIMITED: Huawei, Huawei Modem, BlackBerry, Alcatel MTK, Alcatel U7, Alcatel Modem, LG, Samsung Swift, Samsung 3G, ZTE Qcom-Android, ZTE MTK, and many many more..

There is also a number of services online that offer remote paid services to Unlock any smart phone remotely by paying with a card and providing the IMEI.
I guess this services either use Android Emulator with manually setting the respective IMEI of the phone and then uses some software (box) as they call it to generate the code using the respective algorithm. etc.

 

However as I didn't wanted to spend money on something on such non-sense I digged a little bit more and I found out that according to Bulgarian Legislation encoding a sold mobile phone by the mobile operator is already illegal and all mobile operators in Bulgaria (that used some kind of encoding software to prevent a bought phone from them to be used with another mobile operator should provide openly the mobile phone codes freely).

As MTEL had to fit the new wall they made a small online generator Database with Unlock codes for all prior sold mobiles encoded.

I've used the URL (using my website access previosuly freely registered on website in order to track and send free SMS-es in MTEL and check out my mobile phone money balance spent in inbound and inbound calls etc.)

https://www.mtel.bg/unlock-phone

and found out my mobile ZTE according to the imey:

5803701350365278 ZTE Blade III Поставете карта на друг оператор в телефона и директно ще Ви бъде изискан отключващият код.

Just switched on my ZTE Blade 3 phone and inserted the code and got a message it is wrong but immediately I phone able to connect to Telenor (the ex Globul Mobile operator ) Mobile network Voila! 🙂 Hope this helps small article helps someone else too. Enjoy !

Enable TLS 1.2 Internet Explorer / Make TLS 1.1 and TLS 1.2 web sites work on IE howto

Monday, August 1st, 2016

Internet-Explorer-cannot-display-the-webpage-IE-error
 

Some corporate websites and web tools especially one in DMZ-ed internal corporation networks require an encryption of TLS 1.2 (Transport Layer of Security cryptographic protocol)   TLS 1.1 protocol   both of which are already insecure (prone to vulnerabilities).

Besides the TLS 1.2 browser requirements some corporate tool web interfaces like Firewall Opening request tools etc. are often are very limited in browser compitability and built to only work with certain versions of Microsoft Internet Explorer like leys say IE (Internet Explorer) 11.

TLS 1.2 is supported across IE 8, 9, 10 and 11, so sooner or later you might be forced to reconfigure your Internet Explorer to have enabled the disabled by OS install TLS 1.2 / 1.1.

For those unaware of what TLS (Transport Layer of Security) protocol is so to say the next generation encryption protocol after SSL (Secure Socket Layer) also both TLS and SSL terms are being inter-exchangably used when referring with encrypting traffic between point (host / device etc.) A and B by using a key and a specific cryptographic algorithm.
TLS is usually more used historically in Mail Servers, even though as I said some web tools are starting to use TLS as a substitute for the SSL certificate browser encryption or even in conjunction with it.
For those who want to dig a little bit further into What is TLS? – read on technet here.

I had to enable TLS on IE and I guess sooner others will need a way to enable TLS 1.2 on Internet Explorer, so here is how this is done:
 

Enable-Internet-Explorer-TLS1.2-TLS-1.1-internet-options-IE-screensho
 


    1. On the Internet Explorer Main Menu (press Alt + F to make menu field appear)
    Select Tools > Internet Options.

    2. In the Internet Options box, select the Advanced tab.

    3. In the Security category, uncheck Use SSL 3.0 (if necessery) and Check the ticks:

    Use TLS 1.0,
    Use TLS 1.1 and Use TLS 1.2 (if available).

    4. Click OK
   
     5. Finally Exit browser and start again IE.

 

Once browser is relaunched, the website URL that earlier used to be showing Internet Explorer cannot display the webpagre can't connect / missing website error message will start opening normally.

Note that TLS 1.2 and 1.1 is not supported in Mozilla Firefox older browser releases though it is supported properly in current latest FF releases >=4.2.

If you  have fresh new 4.2 Firefox browser and you want to make sure it is really supporting TLS 1.1 and TLS 1.2 encrpytion:

 

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste TLS and pause while the list is filtered

(3) If the security.tls.version.max preference is bolded and "user set" to a value other than 3, right-click > Reset the preference to restore the default value of 3

(4) If the security.tls.version.min preference is bolded and "user set" to a value other than 1, right-click > Reset the preference to restore the default value of 1

The values for these preferences mean:

1 => TLS 1.0 2 => TLS 1.1 3 => TLS 1.2


To get a more concrete and thorough information on the exact TLS / SSL cryptography cipher suits and protocol details supported by your browser check this link


N.B. ! TLS is by default disabled in many latest version browsers such as Opera, Safari etc.  in order to address the POODLE SSL / TLS cryptographic protocol vulnerability

Change website .JS .PHP Python Perl CSS etc. file permissions recursively for Better Tightened Security on Linux Webhosting Servers

Friday, October 30th, 2015

change-permissions-recursively-on-linux-to-protect-website-against-security-breaches-hacks

It is a common security (breach) mistake that developers or a web design studio make with dedicated or shared hosted websites do to forget to set a nice restrictive file permissions.

This is so because most people (and especially nowdays) developers are not a security freaks and the important think for a programmer is to make the result running in shortest time without much caring on how secure that is.
Permissions issues are common among sites written in PHP / Perl / Python with some CSS and Javascript, but my observations are that JavaScript websites especially that are using some frameworks such as Zend / Smarty etc. and are using JQuery are the most susceptible to suffer from permission security holes such as the classic 777 file permissions, because of developers who’re overworking and pushed up for a deadlines to include new functionality on websites and thus often publish their experimental code on a Production systems without a serious testing by directly uploading the experimental code via FTP / WinSCP on Production system.

Such scenarios are very common for small and middle sized companies websites as well as many of the hobbyist developers websites running on ready CMS system platforms such as Joomla and WordPress.
I know pretty well from experience this is so. Often a lot of the servers where websites are hosted are just share-servers without a dedicated sysadmin and thus there are no routine security audits made on the server and the security permissions issue might lead to a serious website compromise by a cracker and make your website quickly be banned from Google / Yahoo / Ask Jeeves / Yandex and virtually most of Search Engines because of being marked as a spammer or hacked webiste inside some of the multiple website blacklists available nowdays.

Thus it is always a good idea to keep your server files (especially if you’re sysadmin) with restrictive permissions by making the files be owned by superuser (root) in order to prevent some XSS or vulnerable PHP / Python / Perl script to allow you to easily (inject) and overwrite code on your website.

1. Checking whether you have a all users read, write, executable permissions with find command

The first thing to do on your server to assure you don’t have a low security permissioend files is:

find /home/user/website -type f -perm 777 -print

You will get some file as an output like:

./www/tpl/images/js/ajax-dynamic-list/js/ajax-dynamic-list.js
./www/tpl/images/js/ajax-dynamic-list/js/ajax_admin.js
./www/tpl/images/js/ajax-dynamic-list/js/ajax_teams.js
./www/tpl/images/js/ajax-dynamic-list/js/ajax.js
./www/tpl/images/js/ajax-dynamic-list/js/ajax-dynamic-list_admin.js
./www/tpl/images/js/ajax-dynamic-list/lgpl.txt

2. Change permissions recursively to read, write and exec for root and read for everybody and set all files to be owned by (root) superuser

Then to fix the messy permissions files a common recommended permissions is 744 (e.g. Read / Write and Execute permissions for everyone and only read permissions for All Users and All groups).
Lets say you want to make files permissions to 744 just for all JavaScript (JQuery) files for a website, here is how:

find . -iname ‘*.js’ -type f -print -exec chown root:root ‘{}’ \;
find . -iname ‘*.js’ -type f -print -exec chmod 744 ‘{}’ \;

First find makes all Javascript files be owned by root user / group and second one sets all files permissions to 744.

To make 744 all files on server (including JPEG / PNG Pictures) etc.:

find . -iname /home/users/website -type f -print -exec chown root:root ‘{}’ \;
find . -iname /home/users/website -type f -print -exec chmod 744 ‘{}’ \;
