Now this is an interesting turn of events, the Asprox botnet malware is being used to spread SQL Injection tools rather than sending out phishing e-mails as before.
It seems to install quite stealthily as well disguising itself as a Windows Service with a fairly convincing file name. It’s certainly interesting to see the evolution of this kind of malware, what will be next?
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.
The bad news is not many AV vendors are detecting it yet, it seems like it’s just another avenue or infection vector for the Asprox malware. It injects an iFrame into vulnerable pages which will lead to the download of the Asprox infector.
Storm did a variation of this as mentioned via FTP.
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.
It seems like a fairly small scale infection for now, but it’s definitely a worrying trend. It seems like the bad guys are definitely keeping up with the latest vulnerabilities in web apps and online languages and they are utilizing them to spread their wares.
