A botnet is outfitting its army of compromised computers with a SQL 
injection attack tool to hack Web sites, researchers at SecureWorks have 
discovered.

According to SecureWorks, the Asprox botnet, once used solely to send 
out phishing e-mails, is pushing the tool out to systems in its network 
via a binary with the file name msscntr32.exe. The executable is 
installed as a system service with the name "Microsoft Security Center 
Extension."

Despite the name, the file is in fact a SQL injection attack tool that 
when launched searches Google for .asp pages that contain certain terms. 
It then launches SQL injection attacks against the Web sites returned by 
the search. According to SecureWorks, the attack is designed to inject 
an IFrame into the Web site that tricks visitors into downloading a 
JavaScript file from the domain direct84.com.

This file in turn redirects computers to a site where additional 
malicious JavaScripts are stored, although the secondary site appeared 
to be down when SecureWorks first reported the attacks May 14. When 
successful, however, the site installs additional copies of Asprox, the 
password-stealing Trojan Danmec or the SQL attack tool.

According to a list from VirusTotal, only a handful of the major 
anti-virus vendors are detecting the attack tool at this time.

"This is the first time I've seen a SQL injection tool, but certainly 
other botnets have tried to spread in a similar manner, infecting Web 
sites with IFrames," said Joe Stewart, director of malware research at 
SecureWorks. "For instance, Storm tries to get your password if you log 
in to a Web site with FTP, and will put an IFrame into the page for 
you."

So far, SecureWorks has found 1,000 Web sites infected by this wave of 
SQL attacks. Visitors to these infected Web sites are infected with the 
Asprox malware.turning them into bots.and also download some scareware.

"We've estimated [the Asprox botnet] at around 15,000 hosts, but that 
was before the wave of SQL attacks," Stewart said in an interview with 
eWEEK.

Researchers are still investigating exactly what vulnerability on the 
Web sites is being exploited, Stewart said. The Web sites are 
English-language and their owners include law firms and midsize 
businesses.

A similar attack technique is currently being seen spreading 
game-password-stealing Trojans from China. Whether the tool is related 
or only the attack syntax is shared, it is clear that SQL injection 
attack activity is on the rise from multiple sources, Stewart wrote in 
his blog.
