Security Firm Discovers Mac OS X Crimeware Kit

Kara Reeder

Mac users should brace for an avalanche of new information-stealing malware attacks, warns Danish IT security vendor CSIS Security Group. According to, the group has discovered what it claims to be the first crimeware kit aimed at the Mac OS X platform.


The kit, which goes by the name Weyland-Yutani BOT, is being sold on underground forums for $1,000 and is already fully operational, says CSIS. In a blog post, the group claims:

The Weyland-Yutani BOT supports web injects and form grabbing in Firefox; however both Chrome and Safari will soon follow. The webinjects templates are identical to the ones used in Zeus and Spyeye.

The post adds:

CSIS finds this crimekit to be quite disturbing news since MacOS previously to some degree has been spared from the increasing amount of malware which has haunted Windows-based systems for years. This could have resulted in a false sense of security that might make Mac OS user especially vulnerable to a sudden and highly sophisticated attack.
