Zombies blend in with the crowd

Zombies blend in with the crowd

My security colleague, Joris Evers, reported on about new methods botnet operators are using to hide their networks within real-world traffic. Botnets are groups of compromised desktop computers (zombies) which, in large numbers, can be used to attack corporate networks, or to make profits from click-to-view Web advertising. Botnets are typically controlled via Internet Relay Chat (IRC) commands, but as Joris discovered, some are now using Web-based techniques, making detection much harder.
