Webpages of the US Consulate General in St. Petersburg, Russia, were infected by malware earlier this week. The US consulate site was caught up in a much larger hack attack and is not thought to have been targeted as such.

The infected pages have since been cleaned up, reports net security firm Sophos which monitored results of the assault.

The attack on the US consulate was part of a larger campaign by cybercriminals targeting vulnerable web servers. The majority of the 400 compromised web pages hit by the attack were hosted in Russia. Hackers planted malicious scripts on compromised hosts.

After retrieving a copy of one of the infected Consulate pages from an internet cache, virus analysts as Sophos were able to identify the malware script planted on the site as Mal/ObfJS-C, a strain of web nasty that attempts to load further malware from a remote server. This malware includes a Trojan downloader script that attempts to plant backdoor code onto the PCs of surfers with vulnerable machines who visit infected sites.

The attack is described in much greater depth in Sophos's blog here. ®
