Cybercriminals are using a modified version of the ZeuS computer Trojan that no longer relies on command and control servers for receiving instructions. A new variant recently detected by antivirus vendor Symantec has completely removed the need for C&C servers. Every infected computer is now capable of downloading commands, configuration files, and executables from other bots. This makes their botnet more resilient to takedowns, and it also prevents botnet tracking systems like ZeusTracker from doing their job. Researchers have yet to figure out how it sends the captured information back to the attackers.”]
