Once again, Monster.com has been hit by hackers. The job search site was hit by an IFRAME that linked to a malicious site. The attack took advantage of a cross-site scripting vulnerability and was most likely created using Neosploit.

The malware was designed to make computers running it part of a spamming network," the site said in a statement. "The virus is detectable by most major anti-virus software, and this issue should not affect users running Windows with the most recent security updates from Microsoft. In addition, we believe only an extremely small percentage of those using the site this week were potentially exposed prior to those pages being cleaned."

Experts believe that the Russian Business Network. an ISP providing a safe haven for cybercriminals, is to blame.
