SQL injection attack hits hundreds of thousands of web pages

The attack appears to take advantage of features of Microsoft SQL Server, though according to security vendor F-Secure the problem lies in poor site coding, not in vulnerabilities in Microsoft's software. SQL injection is a well-known technique for attacking sites, and one that professional web developers should know they need to guard against.

Affected sites include some operated by the United Nations and the US, UK and Australian governments or their agencies.

According to F-Secure, the domains hosting the malicious content ultimately delivered by the hack are nmidahena.com, aspder.com and nihaorr1.com.

Some reports have suggested the problem is linked to an unpatched flaw in IIS that surfaced last week, but Microsoft has categorically denied that is the case. "We have also determined that these attacks are in no way related to Microsoft Security Advisory (951306)," wrote communications manager Bill Sisk in the Microsoft Security Response Center blog.

"The attacks are facilitated by SQL injection exploits and are not issues related to IIS 6.0, ASP, ASP.Net or Microsoft SQL technologies," he added.
