This case is a great example of one of the core practices when profiling cybercrime incidents and campaigns -> sample everything, as what you're originally seeing is just the tip of the iceberg.

Malware-Serving "Who's Viewed Your Facebook Profile" Campaign Spreading Across Facebook

A currently ongoing Facebook spreading malware-serving campaign, entices users into downloading and executing a malicious executable, pretending to be a "Who's Viewed Your Facebook Profile" extension. In reality though, the executable, part of a campaign that's been ongoing for several months, will steal private information from local browsers, will auto-start on Windows starup, and will attempt to infect all of the victim's friends across Facebook.

The executable, including several other related executables part of the campaign, are currently hosted on Google Code, and according to Google Code's statistics, one of the malicious files has already been downloaded 1,870,788 times. Surprisingly, the Coode Project is called "Project Don't Download". Very interesting self-contradicting social engineering attempt.

Let's dissect the campaign, list the domain's portfolio used in it, provide detection rates for the malicious executables, and connect the campaign to multiple other campaigns observed in the wild over the last couple of weeks.
