Our HackAlert 24x7 Website malware monitoring platform today indicated that mysql.com has been hacked and is currently serving malware. The highlighted section of the above screenshot is the injected script. Below is a video showing how visitors are infected when navigating to the site:


[Infection Chain]

Step 1: http://www.mysql.com

Causes the visiting browser to load the following:

Step 2: http://mysql.com/common/js/s_code_remote.js?ver=20091011

This is the injection point. The entire content of the above .js file can be found here.

The injected section is shown in the above screenshot. The decoded version is as follows:

The text version is available here. This script generates an iframe to Step 3.

Step 3: http://falosfax.in/info/in.cgi?5&ab_iframe=1&ab_badtraffic=1&antibot_hash=1255098964&ur=1&HTTP_REFERER=http://mysql.com/

Throws out a 302 redirect to Step 4.

Step 4: http://truruhfhqnviaosdpruejeslsuy.cx.cc/main.php

This domain hosts the BlackHole exploit pack. It exploits the visitor's browsing platform (the browser, the browser plugins like Adobe Flash, Adobe PDF, etc, Java, ...), and upon successful exploitation, permanently installs a piece of malware into the visitor's machine, without the visitor's knowledge. The visitor doesn't need to click or agree to anything; simply visiting mysql.com with a vulnerable browsing platform will result in an infection.

Currently, 4 out of 44 vendors on VirusTotal can detect this piece of malware.
