"The Asprox botnet, a relatively small botnet known mainly for sending phishing emails, has been spotted in the last few days installing an SQL injection attack tool on its bots. The bots then Google for .asp pages with specific terms -- and then hit the sites found in the search return with SQL injection attacks, says Joe Stewart, director of malware research for SecureWorks, who has documented his findings on the attack.
Stewart says the Asprox botnet’s SQL injection attack is likely a copycat of the recent SQL injection Website attacks from China, which deliver a Trojan that steals online gaming passwords. But this is the first SQL injection attack Stewart has seen using a botnet and a toolkit to do the dirty work. Asprox so far has infected over 1,000 Websites this way, he says.
