‘Indestructible’ Botnet Enslaves 4.5mn PCs

A new and sophisticated botnet has infected more than four million computers in just three months, and it is almost “indestructible”, say security researchers. The botnet, called TDL-4, targets PCs running on Windows and tries hard to avoid detection and even harder to shut down.

TDL-4 is the name for both the Trojan virus that affects machines and the network of compromised computers. “It is the most sophisticated threat today… practically indestructible,” Kaspersky Lab’s security researchers Sergey Golovanov and Igor Soumenkov have stated in a detailed analysis released recently.
