Facebook Spreading, Amazon AWS/Cloudflare/Google Docs Hosted Campaign, Serves P2P-Worm.Win32.Palevo

I've recently spotted a malicious, cybercrime-friendly SWF iframe/redirector injecting service, that also exposes a long-run Win32.Nixofro serving malicious infrastructure, currently utilized for the purpose of operating a rogue social media service provider, that's targeting Turkish Facebook users through the ubiquitous social engineering vector, for such type of campaigns, namely, the fake Adobe Flash player.

Let's profile the service, discuss its relevance in the broader context of the threat landscape, provide actionable/historical threat intelligene on the malicious infrastructure, the rogue domains involved in it, the malicious MD5s served by the cybercriminals behind it, and directly link it to a previously profiled Facebook spreading P2P-Worm.Win32.Palevo serving campaign.

The managed SWF iframe/redirector service, is a great example of a cybercrime-as-a-service type of underground market proposition, empowering, both, sophisticated and novice cybercriminals with the necessary (malvertising) 'know-how', in an efficient manner, directly intersecting with the commercial availability of sophisticated mass Web site/Web server malicious script embedding platforms.

The managed SWF iframe/redirector injecting service is currently responding to 108.162.197.62 and 108.162.196.62 Known to have responded to the same IPs (108.162.197.62; 108.162.196.62) is also a key part of the malicious infrastructure that I'll expose in this post, namely hizliservis.pw - Email: furkan@cod.com.

Here's comes the interesting part. The fine folks at ExposedBotnets, have already intercepted a malicious Facebook spreading campaign, that's using the already profiled in this post videotr.in.

Having directly connected the cybercrime-friendly SWF iframe/redirector injecting service, with hizliservis.pw as well as the SocialMediaSystem as being part of the same malicious infrastructure, it's time to profile the fraudulent/malicious adversaries behind the campaigns. The cybercriminals behind these campaigns, appear to be operating a rogue social media service, targeting Facebook Inc.

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.
