Regcast training : Hyper-V 3.0, VM high availability and disaster recovery

The compromise of legitimate websites with hostile code ultimately designed to serve up malware onto the PCs continues apace, with the latest victims including the Indian embassy in Spain.

Security researchers Ismael Valenzuela (here) and later Dancho Danchev (here) discovered that the the Indian Embassy in Spain was serving malware through an injected malicious iFrame.

Analysis of the Indian Embassy assault by Trend Micro revealed that the attack was part of a wider code injection push that's either an "advertisement scam or a massive malware attack in its early stages".

The code inserted into the compromised websites injects pages that look like blog entries into the compromised sites' domain, linking to illicit pharmaceutical websites. The purpose of the attack could be either to raise the search engine ranking of malvertised websites or a plot to use the legitimate domains of the compromised websites in order to evade spam filters.

Since the websites involved are already compromised, simply modifying tags would turn the seemingly "non-malicious" injection of code into a full-blown malware attack, Trend Micro warns.

In other separate examples of code injection attacks, the Times of India website was infected by malicious code identified by Sophos as Badsrc-C. The Russian Pravda website has also become infected with malicious scripts, Sophos reports, but fortunately this is not pointing at a website currently serving up further malware.

Circumstantial evidence suggest the three attacks are only related via the use of similar techniques.

"The three attacks are directing people to different malign sites using techniques such as SQL injection, to plant code of legitimate sites left open to attack," explained Graham Cluley, senior technology consultant at Sophos. ®
