Cyberattacks October 2012 Part (II) – A very Social Malware (Facebook??)

Despite Facebook being not a new attack vector, there is a new kind of malware spreading through Facebook. This malware is protected against both debugging and network traffic analysis. In order to protect binary code from reverse engineering, it was obfuscated using a special Protector. Network traffic is encrypted (even the DNS queries!) and produced in excess. VirusTotal results for this malware sample:

It spreads through Facebook, by writing a chat short chat message and posting following message on a wall:

http://xxxxxxxx.com/xxxxxxxx.php?ref=facebook&w=%5Brandom characters]&resource=youtube&w=[name] :* favourite [random characters] 😀

Then, it sends a following Skype message:

youtube favourite [random characters]! http://xxxxxxxx.com/xxxxxxxx.php?ref=facebook&w=%5Brandom characters]&resource=youtube&w=[name]

Finally, it sends an MSN message
