Finding spam sending php scripts on multiple sites servers – Tracing and stopping spammer PHP scripts

Monday, April 14th, 2014

stop_php_mail-spam-find-spammer-and-stop-php-spammer-websites
Spam has become a severe issue for administrators, not only for mail server admins but also for webshosting adms. Even the most secure spam protected mail server can get affected by spam due to fact it is configured to relay mail from other servers acting as web hosting sites.

Webhosting companies almost always suffer seriously from spam issues and often their mail servers gets blocked (enter spam blacklists), because of their irresponsible clients uploading lets say old vulnerable Joomla, WordPress without Akismet or proper spam handling plugin,a CMS which is not frequently supported / updated or custom client insecure php code.

What I mean is Shared server A is often configured to sent mail via (mail) server B. And often some of the many websites / scripts hosted on server A gets hacked and a spam form is uploaded and tons of spam start being shipped via mail server B.

Of course on mail server level it is possible to configure delay between mail sent and adopt a couple of policies to reduce spam, but the spam protection issue can't be completely solved thus admin of such server is forced to periodically keep an eye on what mail is sent from hosting server to mail server.
 


If you happen to be one of those Linux (Unix) webhosting admins who find few thousand of spammer emails into mail server logs or your eMail server queue and you can't seem to find what is causing it, cause there are multiple websites shared hosting using mainly PHP + SQL and you can't identify what php script is spamming by reviewing  Apache log / PHP files. What you can do is get use of:

PHP mail.log directive

Precious tool in tracking spam issues is a PHP Mail.log parameter, mail log paramater is available since PHP version >= 5.3.0 and above.
PHP Mail.log parameter records all calls to the PHP mail() function including exact PHP headers, line numbers and path to script initiating mail sent.

Here is how it is used:
 

1. Create empty PHP Mail.log file

touch /var/log/phpmail.log

File has to be writtable to same user with which Apache is running in case of Apache with SuPHP running file has to be writtable by all users.

On Debian, Ubunut Linux:

chown www:data:www-data /var/log/phpmail.log

On CentOS, RHEL, SuSE phpmail.log has to be owned by httpd:

chown httpd:httpd /var/log/phpmail.log

On some other distros it might be chown nobody:nobody etc. depending on the user with which Apache server is running.

 

2. Add to php.ini configuration following lines

mail.add_x_header = On
mail.log = /var/log/phpmail.log

PHP directive instructs PHP to log complete outbund Mail header sent by mail() function, containing the UID of the web server or PHP process and the name of the script that sent the email;
 

(X-PHP-Originating-Script: 33:mailer.php)


i.e. it will make php start logging to phpmail.log stuff like:
 

 

mail() on [/var/www/pomoriemonasteryorg/components/com_xmap/2ktdz2.php:1]: To: info@globalremarketing.com.au — Headers: From: "Priority Mail" <status_93@pomoriemon

e;boundary="———-13972215105347E886C13F2"

 

On Debian / Ubuntu Linux to enable this logging, exec:

echo 'mail.add_x_header = On' >> /etc/php5/apache2/php.ini
echo 'mail.log = /var/log/phpmail.log' >> /etc/php5/apache2/php.ini


I find it useful to symlink /etc/php5/apache2/php.ini to /etc/php.ini its much easier to remember php location plus it is a standard location for many RPM based distros.

ln -sf /etc/php5/apache2/php.ini /etc/php.ini

Or another "Debian recommended way" to enable mail.add_x_header logging on Debian is via:

echo 'mail.add_x_header = On' >> /etc/php5/conf.d/mail.ini
echo 'mail.log = /var/log/phpmail.log' >> /etc/php5/conf.d/mail.ini

On Redhats (RHEL, CentOS, SuSE) Linux issue:

echo 'mail.add_x_header = On' >> /etc/php.ini
echo 'mail.log = /var/log/phpmail.log' >> /etc/php.ini

3. Restart Apache

On Debian / Ubuntu based linuces:

/etc/init.d/apache2 restart

P.S. Normally to restart Apache without interrupting client connections graceful option can be used, i.e. instead of restarting do:

/etc/init.d/apache2 graceful

On RPM baed CentOS, Fedora etc.:

/sbin/service httpd restart

or

apachectl graceful
 

4. Reading the log

To review in real time exact PHP scripts sending tons of spam tail it:

tail -f /var/log/phpmail.log

 

mail() on [/var/www/remote-admin/wp-includes/class-phpmailer.php:489]: To: theosfp813@hotmail.com — Headers: Date: Mon, 14 Apr 2014 03:27:23 +0000 Return-Path: wordpress@remotesystemadministration.com From: WordPress Message-ID: X-Priority: 3 X-Mailer: PHPMailer (phpmailer.sourceforge.net) [version 2.0.4] MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset="UTF-8"

As you can see there is a junky spam mails sent via some spammer script uploaded under name .3a1a1c.php, so to stop the dirty bastard, deleted the script:

rm -f /var/www/pomoriemonasteryorg/media/rsinstall_4de38d919da01/admin/js/tiny_mce/plugins/inlinepopups/skins/.3a1a1c.php

It is generally useful to also check (search) for all hidden .php files inside directoring storing multiple virtualhost websites, as often a weirdly named hidden .php is sure indicator of either a PHP Shell script kiddie tool or a spammer form.

Here is how to Find all Hidden Perl / PHP scripts inside /var/www:

find . -iname '.*.php'
./blog/wp-content/plugins/fckeditor-for-wordpress-plugin/ckeditor/plugins/selection/.0b1910.php
./blog/wp-content/plugins/fckeditor-for-wordpress-plugin/filemanager/browser/default/.497a0c.php
./blog/wp-content/plugins/__MACOSX/feedburner_feedsmith_plugin_2.3/._FeedBurner_FeedSmith_Plugin.php

find . -iname '.*.pl*'

….

Reviewing complete list of all hidden files is also often useful to determine shitty cracker stuff

 find . -iname ".*"

Debugging via  /var/log/phpmail.log enablement is useful but is more recommended on development and staging (QA) environments. Having it enable on productive server with high amounts of mail sent via PHP scripts or just on dedicated shared site server could cause both performance issues, hard disk could quickly get and most importantly could be a severe security hole as information from PHP scripts could be potentially exposed to external parties.

How to clean QMAIL mail server filled Queue with spam mail messages

Friday, June 8th, 2012

Sys Admins managing QMAIL mail servers know, often it happens QMAIL queue gets filled with unwanted unsolicated SPAM e-mails due to a buggy WEB PHP / Perl mail sendingform or some other odd reason, like too many bouncing messages ,,,,

For one more time I’ve experienced the huge SPAM destined mails queue on one QMAIL running on Debian GNU / Linux.

= … Hence I needed to clean up the qmail queue. For this there is a little tool written in PERL called qmhandle

A+) Download qmhandle;

Qmhandle’s official download site is in SourceForge

I’ve made also a mirror copy of QMHandle here

qmail-server:~# cd /usr/local/src
qmail-server:/usr/local/src# wget -q http://www.pc-freak.net/files/qmhandle-1.3.2.tar.gz

B=) STOP QMAIL
As it is written in the program documentation one has to be very careful when cleaning the mail queue. Be sure to stop qmail with qmailctl or whatever script is used to shutdown any mail sever in progress operations, otherwise there is big chance the queue to mess up badly .

C#) Check extended info about the mail queue:

qmail-server:/usr/local/src/qmhandle-1.3.2# ./qmhandle -l -c

How to change users quota to NO QUOTA on Qmail with Vpopmail Mail server install / Qmail mail over quota issue

Monday, February 20th, 2012

 

Qmail Vpopmail quota exceeded Dolphin Logo

Already on a couple of mail boxes located on one of the qmail powered mail servers I adminiter, there is an over QUOTA reached problem encountered.

Filling up the mailbox quota is not nice as mails starts get bounced back to the sender with a message QUOTA FULL or EXCEEDED MESSAGE, if this is a crucial mail waiting for some important data etc. the data is never received.
Below is a copy of the mail quota waarning notification message:

Delivered-To: email_use@my-mail-domain.net
Date: Wed, 15 Feb 2012 17:40:36 +0000
X-Comment: Rename/Copy this file to ~vpopmail/domains/.quotawarn.msg, and make appropriate changes
X-Comment: See README.quotas for more information
From: Mail Delivery System <Mailer-Daemon@different.bg>
Reply-To: email@pc-freak.net
To: Valued Customer:;
Subject: Mail quota warning
Mime-Version: 1.0
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 7bit
>
Your mailbox on the server is now more than 90% full. So that you can continue
to receive mail you need to remove some messages from your mailbox.

As you can read from the copy of the mail message above, the message content sent to the mail owner whose quota is getting full is red from /var/vpopmail/domains/.quotawarn.msg

The mail reaching quota problem is very likely to appear in cases like low mailbox quota set, but sometimes also occurs due to bugs in vpopmail quota handling.

Various interesting configuration settings for mail quotas etc. are in /home/vpopmail/etc/vlimits.default file, (assuming vpopmail is installed in /home).

In my specific case, the default vpopmail mailbox quota size was set to only 40 Megabytes.
40MB is too low if compared to todays mailbox size standards which in Gmail and Yahoo  mail services are already a couple of gigabytes.
Hence to get around the quota troubles, I  removed the quota for the mail.
To remove the quota size in vpopmail set for address (email_user@my-mail-domain.net) used cmd:

qmail-server:~# vmoduser -q NOQUOTA email_user@my-mail-domain.net

To save myself from future quota issues, I decided to apply a permanent fix to all those over quota size VPOPMAIL mailbox problems by removing completely quota restriction for all mailboxes in my vpopmail existent mail domain.

To do so, I wrote a quick simple bash loop one-liner script:

qmail-server:~# cd /home/vpopmail/domains
qmail-server:~/vpopmail/domains# cd my-mail-domain.net
qmail-server:~/vpopmail/domains/my-mail-domain.net# for i in *; do \
vmoduser -q NOQUOTA $(echo $i|grep -v vpasswd)@my-mail-domain.net; \
done

This works only on vpopmail installations which are configured to store the mail messages directly on the filesystem. Therefore this approach will not work for people who during vpopmail install had configured it to store mailboxes in MySQL or in other kind of SQL db engine.

Anyways for Vpopmail installed to use SQL backend, the script can be changed to read directly a list with all the mailboxes obtained from databasae (SQL query) and then, loop over each of the mail addresses apply the vmoduser -q NOQUOTA mail@samplemaildomain.net.

I've written also a few lines shell script (remove_vpopmail_emails_domain_quota.sh), it accepts one argument which is a vpopmail domain to which the admin would like to reset all applied mailbox quotas. The script is useful, if you have to often remove all quotas for vpopmail domainsor have to do quota wipe out simultaneously for multiple email domain names  located on different servers.

Easy way to look for irregularities and problems in log files / Facilitate reading log files on GNU / Linux and FreeBSD

Thursday, November 24th, 2011

LogWatch logo picture check Logcheck Linux BSD look for irregularities in log files

As a System Administrator I need to check daily the log files produced on various GNU / Linux distributions or FreeBSD. This can sometimes take too much time if the old fashioned way using the normal system tools cat, less and tail etc. is used.

Reading logs one by one eats too much of my time and often as logs are reviewed in a hurry some crucial system irregularities, failed ssh or POP3 / Imap logins, filling disk spaces etc. are missed.

Therefore I decided to implement automated log parsing programs which will summary and give me an overview (helicopter view) on what were the system activities from the previous day (24h) until the moment I logged the system and issued the log analyzer program.
There are plenty of programs available out there that does “wide scale” log analysis, however there are two applications which on most GNU / Linux and BSD systems had become a de-facto standard programs to scan system log files for interesting lines.

These are:
 

  • 1. logwatchsystem log analyzer and reporter
  • 2. logcheckprogram to scan system log files for interesting lines

1. logwatch is by default installed on most of the Redhat based Linux systems (Fedora, RHEL, CentOS etc.). On Debian distributions and as far as I know (Ubuntu) and the other deb based distros logwatch is not installed by default. Most of the servers I manage these days are running Debian GNU / Linux so, to use logwatch I needed to install it from the available repository package, e.g.:

debian:~# apt-get install logwatch
...

logwatch is written in perl and with some big files to analyze, parsing them might take hell a lot of time. It does use a bunch of configuration scripts which defines how logwatch should read and parse the various services logwatch support by default. These conf scripts are also easily extensible, so if one has to analyze some undefined service in the conf files he can easily come up with a new conf script that will support the service/daemon of choice.Using logwatch is very easy, to get an overview about server system activity invoke the logwatch command:

debian:~# logwatch
################### Logwatch 7.3.6+cvs20080702-debian (07/02/08) ####################

###################### Logwatch End #########################

The execution might take up from 10 to 20 seconds up to 10 or 20 minutes depending on the log files size and the CPU / RAM hardware on the machine where /var/log/… logs will be analyzed.

logwatch output can be easily mailed to a custom mail address using a crontab if the server runs a properly configured SMTP server. Using a cron like:

00 5 * * * /usr/sbin/logwatch | mail -s "$(hostname) log files for $(date)"

Here is time to make a note that logwatch is ported also to FreeBSD and is available from BSD’s port tree, from a port with path:

/usr/ports/security/logcheck

2. logcheck is another handy program, which does very similar job to logwatch . The “interesting” information it returns is a bit less than compared to logwatch

The good thing about logcheck is that by default it is made to mail every 1 hour a brief data summary which might be of an interest to the sys admin.
Logcheck is available for install on RedHat distros via yum and has existing package for Debian as well as a port for FreeBSD under the port location /usr/ports/security/logcheck

To install on logcheck on Debian:

debian:~# apt-get install logcheck
...

After installation I found it wise to change the default mailing time from each and every hour to just once per day to prevent my email from overfilling with “useless” mails.

This is done by editting the default cron tab installed by the package located in /etc/cron.d/logcheck

The default file looks like so:

# /etc/cron.d/logcheck: crontab entries for the logcheck package
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
@reboot logcheck if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck -R; fi
2 * * * * logcheck if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck; fi
# EOF

To change it run only once per day its content should looks something like:

# /etc/cron.d/logcheck: crontab entries for the logcheck package
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
@reboot logcheck if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck -R; fi
2 5 * * * logcheck if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck; fi
# EOF

Altering it that way the log summary interesting info analysis will be sent on mail every day in 05:02 a.m.
Changing the default email logcheck will ship its log analyzer report emails on deb based distros is done via editting the file:

/etc/logcheck/logcheck.conf

And changing the SENDMAILTO=”” variable to point to the appropriate admin email email addr.

How to add multi language support to wordpress with qTranslate

Monday, October 3rd, 2011

QTRanslate WordPress Language Translate Screenshot 1

Lately, I have to deal with some wordpress based installs in big part of my working time. One of the wordpress sites needed to have added a multi language support.

My first research in Google pointed me to WPML Multilingual CMS The WordPress Multilingual Plugin
WPML Multilingual CMS looks nice and easy to use but unfortunately its paid, the company couldn’t afford to pay for the plugin so I looked forward online for a free alternative and stumbled upon QTranslate

QTranslate is free and very easy to install. Its installed the wordpress classic way and the installation went smoothly, e.g.:

1. Download and unzip QTranslate

# cd /var/www/blog/wp-content/plugins
/var/www/blog/wp-content/plugins# wget http://downloads.wordpress.org/plugin/qtranslate.2.5.24.zip
...
/var/www/blog/wp-content/plugins# unzip qtranslate.2.5.24.zip
...

Just for fun and in case the plugin disappears in future, a mirror of Qtranslate 2.5.24 is found here

2. Enable QTranslate from wordpress admin

Plugins -> Inactive -> qTranslate (Activate)

After activating the plugin, there is a Settings button from which qTranslate‘s various plugin parameteres can be tuned.

qTranslate WordPress translate screenshot 2

In my case my site had to support both English and Arabic, so from the settings I added support for Arabic translation to the wordpress install.

Adding Arabic is done in the following way:

a. From the Language Management (qTranslate Configuration) from the Languages menu and the Languages (Add Languages) I had to choose a language code (in my case a language code of ar – for Arabic). Next I had to choose the Arabic flag from the follow up flag list.

In next text box Name , again I had to fill Arabic, for Locale en_US.UTF-8
The following Date Format and Time Format text boxes are optional so I left them blank.
To complete the process of adding the Arabic as a new language wordpress should support I pressed the Add Language button and the Arabic got added as a second language.

Afterwards the Arabic was added as second language, on the bottom of the left wordpress menu pane a button allowing a switch between English, Arabic appeared (see below screenshot):

MultiLingual WordPress with qTranslate

Finally to make Arabic appear as a second language of choice on the website I added it as a Widget in the Widgets menu from the AWidgets menu:

Appearance -> Widgets

In widgets I added qTranslate Language Chooser to the Sidebar without putting any kind of Title for qtranslate widget .
I found it most helpful to choose the Text and Image as an option on how to display the Language switching in the wp.

Graphical representation of Open Source history generated from SVN and GIT commits with Gource – Software version control visualization

Thursday, September 1st, 2011

A friend of mine has sent me a link to awesome videos produced with an open source tool called Gource

The tool is really awesome as its capable of producing amazing graphical visualizations from source tree repositories obtained from software SVN or GIT repositories

Someone used it to create a wonderful videos and relate the graphical visualization with wondeful music to show graphically the Software development for the main Free Software Projects. 😉

The points which move around in videos are graphical representation of the repository source, the nodes which buzzle around are users who commit source in the project repositories.
The whole graphical representation is being generated based on all the latest source hold inside the software repository, on top of the videos its visible the date of each of the source commits.
Below are few of the nice videos, the rest are available for checkout in Youtube, Enjoy! 😉

OpenOffice Development – Graphical representation

PHP Development – Graphical representation

History of Python development since 1990 with Gource

Development of MySQL 2000-2010 – Graphical representation

Perl development history in less then 4 minutes. Visualized with gource.

How to fix wrongly configured timezone in Debian GNU/Linux and Ubuntu

Wednesday, August 3rd, 2011

During the install of a new Debian GNU/Linux server I was in a real hurry, so I mistakenly choose a wrong timezone of US/Pacific

As a consequence the server date and time was incorrect and I had to fix that to adjust to the proper server location which of this case was:Europe/London

Here is the quick fix:

debian:~# dpkg-reconfigure tzdata

Next I choose my timezone from the ncurses interface navigating with arrow keys and used ntpdate to synchronize the time for the server like so:

debian:~# ntpdate time.nist.gov
3 Aug 16:02:26 ntpdate[26658]: adjust time server 192.43.244.18 offset 0.000802 sec

Done 😉
