Trojan:JS/BlacoleRef.DD

Trojan:JS/BlacoleRef.DD is a JavaScript Trojan that spreads via hijacked websites. A hijacked website may permit a cybercriminal to successfully add a client-side script, which then is run when a web user visits the hacked website. Trojan:JS/BlacoleRef.DD is produced to load an obfuscated IFrame that loads behind the victimized computer user's Internet browser, diverting it to an exploit server known as 'Blackhole'. The payload of Trojan:JS/BlacoleRef.DD may be different, based on what the reference host delivers at the time of compromise. The combination of obfuscated JavaScript within a hidden IFrame referencing a malevolent host, and the malevolent host itself, which is responsible for dynamically generated content, which aims at exploiting numerous vulnerabilities on the victim's PC, are controlled and could be changed by a cybercriminal at any time. The reference host is responsible for loading the main exploit code of 'Blackhole', which targets the PC by executing a variety of known and 'zero day' vulnerabilities through the affected Internet browser.
