The do-it-yourself toolkit offers a template for spreading malware, directing users to click-fraud accounts and for pushing Facebook users to bogus surveys to hijack personal information.
"The buyer doesn't have to have development experience with Facebook, he/she just needs to follow the accompanying instructions and a working viral Facebook application is at their disposal," the company explained.
Websense researchers have linked the toolkit, called TinieApp, to the recent "Profile Creeps" and "Creeper Tracker" rogue app attack that appeared on Facebook over the last week.
"This phenomenon of template Facebook applications like Tinie app shows how the spamming culture is consolidating more and more around Facebook, adapting to the platform and increasing what we call Web spam," Websense added.
