A new botnet that has infected 4.5 million Windows PCs is “practically indestructible,” security researchers say. Researchers say TDL-4 has traits that make it extremely tough to detect, delete, suppress or eradicate. The botnet has advanced encryption and the use of a public peer-to-peer network for instructions issued to the malware by command-and-control servers. Researchers: “It does a very good job of maintaining itself. It does very well,” said Dell SecureWorks’ Joe Stewart.”]
