Fake Adobe Flash Player Serving Campaign Utilizes Google Hosting/Redirection Infrastructure, Spreads Across Facebook

What "better" time to spread malicious "joy", then during the Holidays? Cybercriminals are still busy maintaining a fake Adobe Flash Player serving, Facebook spreading campaign, which I originally intercepted during the Holidays, utilizing Google redirectors/hosting services. Despite the modest -- naturally conservative estimate -- click-through rate (45,000 clicks) compared to that of the most recently profiled similar Febipos spreading campaign, which resulted in over 1 million clicks, the campaign remains active, and continues tricking users into installing the rogue Adobe Flash Player, resulting in the continued spread of the campaign, on the Facebook Walls of socially engineered users.

Let's dissect the campaign, expose its infrastructure/command and control servers, and provide MD5s of the served malware.

Continuing Facebook "Who's Viewed Your Profile" Campaign Affects Another 190k+ Users, Exposes Malicious Cybercrime Ecosystem

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.

Continuing Facebook "Who's Viewed Your Profile" Campaign Affects Another 190k+ Users, Exposes Malicious Cybercrime Ecosystem

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.

Facebook Circulating 'Who's Viewed Your Profile' Campaign Exposes 800k+ Users to CrossRider PUA/Rogue Firefox Add-ons/Android Adware AirPush

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.

Fake Chrome/Firefox/Internet Explorer/Safari Updates Expose Users to Android Malware

A currently ongoing malicious campaign using compromised sites as the primary traffic acquisition tactic, is attempting to socially engineer users (English and Russian speaking) into thinking that they're using an outdated version of their browser, and need to apply a bogus (security/antivirus) update. In reality though, the update is a variant of Trojan:Android/Fakeinst.EQ/Android.SmsSend.

Sample screenshots of the fake browser update landing pages:

All samples phone back to dlsdcncnew.net (109.163.230.182; Email: constantin.zawyalov@yandex.ru). Responding to the same IP is also newapk-flv.org.

The same email is also known to have been previously used to register the following domains:

admitted-6crept.org
rufileserver.in

It appears that the traffic is not segmented -- to affect mobile device users only -- at any point of the redirection chain, an indication of what I believe is a boutique cybercrime-friendly operation. In comparison, the relatively more sophisticated ones would segment the traffic, usually acquired through the active exploitation of tens of thousands of legitimate Web sites, or the direct purchase of segmented mobile traffic.

Interestingly, both novice players in this market segment, and the experienced ones, are implementing basic evasive tactics, such as, for instance, the need to provide a valid mobile number, where a potential victim will receive a confirmation code for accessing the inventory of rogue games and applications, thereby preventing automatic acquisition of the apps for further analysis. Moreover, providing a valid mobile number to the cybercriminals behind the campaign, is naturally prone to be abused in ways largely based on the preferences of those who obtained them through such a way, therefore users are advised not to treat their mobile number in a privacy conscious way.
