Showing posts with label Fake Who's Viewed Your Facebook Profile Extension. Show all posts
Last week, immediately after I published the initial analysis detailing a massive privacy-violating "Who's Viewed Your Profile" campaign, that was circulating across Facebook, the cybercriminals behind it, supposedly took it offline, with one of the main redirectors now pointing to 127.0.0.1.
Not surprisingly, the primary campaign has multiple sub-campaigns still in circulation, which based on the latest statistics -- embedded within the campaign on the same day they supposedly shut it down -- has already exposed another 190,000+ of the social network's users -- the original campaign appears to have been launched in 2011 having already exposed 800,000+ users -- to more rogue, privacy violating apps -- JS.Febipos, Mindspark Interactive Network's MyImageConverter and Trojan-Ransomer.CLE, in this particular case.
Let's dissect the still circulating campaign, expose the entire infrastructure supporting it, establish direct connections with it to related malicious campaigns, indicating that someone's either multi-tasking, or that their malicious/fraudulent activities share the same infrastructure, provide MD5s for the currently served privacy-violating apps, as well as list the actual -- currently live -- hosting locations.

Based on the latest performance metrics for the campaign, over 190,000 users have already interacted with this sub-campaign, since 4th of December, when I initially analyzed the primary campaign.
Monitoring of the campaign is naturally in progress. Updates will be posted as soon as new developments take place. Continue reading →
A massive privacy-violating, Facebook circulating "Who's Viewed Your Profile" campaign, has been operating beneath the radar, exposing over 800,000 users internationally, to a cocktail of PUAs (Potentially Unwanted Applications), rogue Firefox Add-ons impersonating Adobe's Flash Player, as well as the Android based adware AirPush.
Relying on a proven social engineering tactic of "offering what's not being offered in general", next to hosting the rogue files on legitimate service providers -- Google Docs and Dropbox in this particular case -- the campaign is a great example that the ubiquitous for the social network social engineering scheme, continues to trick gullible and uninformed users into installing privacy-violating applications on their hosts/mobile devices.
Let's dissect the campaign, expose its infrastructure, (conservatively) assess the damage, and provide fresh MD5s for the currently served privacy-violating PUAs, Firefox add-ons, and Android adware.

Time to (conservatively) assess the campaign's damage over the year(s):
The click-through rate should be considered conservative, and it remains unknown whether the URL shortening service was used by the cybercriminal(s) since day one of the campaign.
The campaign remains active, and is just the tip of the iceberg in terms of similar campaigns tricking Facebook's users into thinking that they can eventually see who's viewed their profile. Facebook users who stumble across such campaigns on their own, or their friends' Walls, are advised to consider reporting the campaign back to Facebook, immediately. Continue reading →
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.
