Internet security specialist Secure Computing has issued a warning of an SQL injection attack that appears to have infected several thousand web servers, including government and financial services sites.
According to a blog on the company's TrustedSource information site, the attack began late last Friday. It targets machines running Microsoft SQL Server.
The post said that “It's also possible that web servers with Sybase database backends could also conceivably be exploited.”
Sybase largely uses the same SQL syntax and table structure as SQL Server.
Visitors to infected web servers could be sent one of many different forms of malware, TrustedSource warned.
“Similar to phishing, this attack takes advantage of the website visitor's trust in the site they are visiting. Instead of phishing for information, however, malware is sent to the client, which the client has a higher likelihood of accepting being from a trusted site,” the company claimed.
This type of attack SQL attack could be used to launch phishing attacks on sites requesting financial information, or any other type of attack where the visitors' trust can be exploited, warned TrustedSource.
“As of today, this attack is still working and ongoing. We are seeing evidence of successful exploitation attempts across hundreds of web pages. These web pages are associated with web sites from around the world and supplying various content including government sites, sales sites, real estate sites, and financial information sites among others,” the company added.
