This month ESET Virus Researchers discovered new information on a new modification in the
Win32/TrojanDownloader.Carberp trojan family.

Evolution of Win32Carberp: going deeper
http://blog.eset.com/2011/11/21/evoluti ... ing-deeper

new Carberp modification use VBR bootkit infector.
At the time the only known malware utilizing the same bootkit component was the Rovnix bootkit
Thanks
Rovnix is the Cidox/Mayachok.2, posted http://www.kernelmode.info/forum/viewto ... =16&p=7094
Overall engine does not seems changed, VBR for example is the same and detected as Cidox/Mayachok - http://www.virustotal.com/file-scan/rep ... 1322031891

Just one note about dropper. It is packed with Mystic Compressor and has a feature to restore possible hooked ntdll.dll routines, this is a trick it uses to fool debugging with breakpoints.
