Symantec researchers have found a new Zeus/SpyEye variant that uses a peer-to-peer architecture rather than a command-and-control server system.

"The P2P network architecture enables the botnet to stay alive and gather information even if portions of the network are shut down, observed Andrea Lelli in a Symantec blog," Infosecurity reports.

"Law enforcement has been able to take down botnets in the past by shutting down the C&C servers," the article states. "However, with a P2P network architecture, a botnet can avoid this single point of vulnerability."
