In an attempt to mitigate the impact of the recent waves of SQL injection attacks, and provide more transparency into the approximate number of affected pages, the Shadowserver Foundation is starting to maintain a list of all the malicious domains used in the continuing efforts by copycats to inject as many legitimate sites as possible. Currently counting over fifty malicious domains, and the corresponding number of affected pages by them, the total number is just over 1.5 million.
Needless to say to stay away from these domains if you don't know what you're doing. The Shadowserver's announcement :
Despite that some of the malicious domains are down, or in a process of getting shut down, as long as the long tail of SQL injection attacks is possible due to vulnerable sites at the far corner of the Web, the bad guys would simple keep re-introducing new domains within, or emphasize on increasing their life cycle by fast-fluxing them as we've already seen this happen.
