The main website for the NBC television network, NBC.com, was found yesterday to have been hacked so that it infected unsuspecting visitors.
Specifically, it harbored the RedKit browser exploit kit, which triggers drive-by downloads of malware onto vulnerable computers.
NBC's problems arose when the head of Dutch security firm Fox-IT tweeted his observations about NBC.com, followed quickly by a posting on the HitmanPro blog run by the Dutch anti-virus firm SurfRight.
"There were two exploit links on the NBC website. The first one was on the main default (entry) page. And the second one was located on hxxp://www.nbc.com/assets/core/js/s_wrapper.js," said the HitmanPro blog. "It serves both Java (CVE-2013-0422) and PDF exploits. The exploit drops the Citadel Trojan, which is used for banking fraud and cyberespionage."
The HitmanPro posting noted that RedKit was also installing the ZeroAccess malware, which "moderates an affected user's Internet experience by modifying search results, and generates pay-per-click advertising revenue for its controllers," as well an unknown form of malware.
An NBC spokeswoman confirmed the hacks to Bloomberg News. All the affected sites were cleaned and back up Friday morning.
