Lately a lot of malwares are using rootkit techniques. Private and antivirus companies are trying to develop tools against malwares but, despite the fact that most of the techniques are well documented around the net, only a few companies are getting positive results. This particular malware is a perfect example because when it came out only a few tools were able to recognize its nasty operations. Don't know what you think but that's sound a little bit strange for me.
Nothing new, nothing special... just a malware analysis from me.
