Over the past few days, we intercepted a malware campaign that spreads through Skype messages, exclusively coming from malware-infected friends or colleagues. Once users click on the shortened link, they’ll be exposed to a simple file download box, with the cybercriminals behind the campaign directly linking to the malicious executable.

More details:

Sample screenshot of the campaign in action:

Skype_Spreading_Malware_Social_Engineering

Sample redirection chain: hxxp://www.goo.gl/aMrTD?image=IMG0540250-JPG -> hxxp://94.242.198.67/images.php -> MD5: f29b78be1cd29b55db94e286d48cddef – detected by 20 out of 46 antivirus scanners as Gen:Variant.Symmi.17255.

More malware is known to have been rotated on the same IP, such as for instance:
hxxp://94.242.198.67/sg0.exeMD5: cfaf9e3345bb6dc7204d6ad1a266a4c0 – detected by 9 out of 46 antivirus scanners as Trojan.FakeSky

hxxp://94.242.198.67/IMG0540250-JPG.scrMD5: f29b78be1cd29b55db94e286d48cddef – detected by 20 out of 46 antivirus scanners as Gen:Variant.Symmi.17255

Upon execution, MD5: d848763fc366f3ecb45146279b44f16a phones back to hxxp://xlotxdxtorwfmvuzfuvtspel.com/RQQgW6RRMZKWdj0xLjImaWQ9MjQ3NzA0MzA5MiZhaWQ9MzAyODcmc2lkPTQmb3M9NS4xLTMyluYwGI8j – 50.62.12.103

What’s so special about this IP (50.62.12.103) anyway? It’s the fact that it’s known to have been used as a C&C for the Madi/Mahdi malware campaign, as well as a C&C for the Flashback MAC OS X malware, proving that someone’s definitely multi-tasking.
