Popular humor site hosted Nuclear Pack exploit kit

November 13, 2013 – 5:04 PM

Cracked.com, a humor website that is among the 300 most popular sites in the U.S., may have left visitors a sobering surprise this week.

According to Barracuda Labs, as of Sunday the website was compromised to host the Nuclear Pack exploit kit.

Daniel Peck, principal research scientist on the security team at Barracuda Labs, told SCMagazine.com on Wednesday that Cracked.com remained infected at least through Monday, though saboteurs may have had access to the site since early last week.

Exploits packaged in the kit were served through a malicious javascript on the site, he explained. And after analyzing the threat, Barracuda researchers found it suspicious that the malware sent requests to a newly registered domain, crackedcdm.com, which was set up Nov. 4.

“There has been some analysis that we did, and it seems that it came from the Nuclear [Pack] attack kit, serving the ZeroAccess malware,” Peck said.

Users running vulnerable versions of Java and Adobe Flash and PDF software, are among those who may have been impacted this week, he said.
