First Seen: January 10, 2013
OS(es) Affected: Windows

Trojan:JS/BlacoleRef.CM is a JavaScript Trojan that spreads via hijacked websites. Trojan:JS/BlacoleRef.CM is created to load a hidden IFrame that loads behind the affected PC user's web browser, diverting it to an exploit server known as 'Blackhole'. Once web users activate any links within IFrames while viewing web content on malicious websites, their PCs get infected with Trojan:JS/BlacoleRef.CM. A compromised website may allow an attacker to successfully insert a client-side script, which then runs when a PC user visits the hacked website. Trojan:JS/BlacoleRef.CM's payload may differ, depending on what the reference host delivers at the time of hijack. The combination of obfuscated JavaScript within a hidden IFrame referencing a malicious host, and the malicious host itself, which is responsible for dynamically generated content aimed at exploiting various vulnerabilities on the victim's computer, are controlled and could be changed by an attacker at any time allowing it to be highly adaptable to the cybercriminal's needs.
