Virus analysts are having a nightmare with this one as it self destructs when it detects efforts at analysis.
“Security researchers at Cisco have published new research on a malware, named Rombertik, which will go out of its way to avoid getting analyzed by deleting essential data in the Windows system file called the Master Boot Record (MBR) sending the computer into an endless reboot loop.
The malware also attempts to fool the researchers' sandboxing tools by writing a random byte of data to the system's memory over 960 million times.” – Neowin
The virus appears to be stupid (apart from that part above) since it steals random info like logons and personal data, but it doesn’t maintain its cover…which is the goal of most spyware: It hooks into your browser taking your info from websites and forms you fill out. It is transmitted through emails with attachments which appear to be some sort of pdf but which is actually a .scr screensaver executable which contains the virus.
