Mother of all Botnets Discovered - TDSS Malware variant TDL-4

According to Kaspersky Lab, a new TDSS rootkit variant called TDL-4 has infected more than 4.5 million PCs worldwide in just the first three months of 2011. The security experts say that this sneaky malware is one of the most technologically sophisticated threats to date. Because of upgrades from the previous TDL-3 incarnation, this new TDL-4 has the ability to create a botnet that is practically ‘indestructible’.
TDL-4 is a bootkit, it infects the master boot record of a PC which allows the code to run before a computer’s operating systems starts up. Doing this allows the malware, along with the programs it downloads, invisibility to operating systems as well as any antivirus programs. 😐
