Our friends at the Internet Storm Center, have solved the mystery of the mass website infection in January pointing to the uc8010.com domain. Computer Associates was one of the victims. It's been confirmed that SQL injection was the vector of attack. Injection attacks are listed as nr. 2 in their OWASP Top Ten Application vulnerabilities.
Full analysis at the ISC.Yesterday, one of our old friends, Dr. Neal Krawetz, pointed us to another site hosting malicious JavaScript files with various exploits. While those exploits where more or less standard, we managed to uncover a rare gem between them – the actual executable that is used by the bad guys in order to compromise web sites.
While we had a general idea about what they do during these attacks, and we knew that they were automated, we did not know exactly how the attacks worked, or what tools the attackers used. The strategy was relatively simple: they used search engines in order to find potentially vulnerable applications and then tried to exploit them. The exploit just consisted of an SQL statement that tried to inject a script tag into every HTML page on the web site.
The utility we recovered does the same thing. The interface appears to be is in Chinese so it is a bit difficult to navigate around the utility, but we did some initial analysis of the code (which is very big) to confirm what it does.
