They've been available for Windows platforms for several years now, so it was kind of inevitable that one would eventually be made for OS-X. It basically makes it easy for griefers to make trojans, presumably for botnet and similar things. It runs on Windows but has the option of generating binaries for OS-X. And here's some more joy: ""The kit is being sold under the name Weyland-Yutani BOT and it is the first of its kind to hit the Mac OS platform. Basically it's a GUI point & click interface to create payloads that are script kiddie friendly.
Apparently, a dedicated iPad and Linux release are under preparation as well. 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.""
