FSecure sees smaller botnets on the rise

Cybercriminals are downsizing their botnets to make it harder for software security companies to track and contain botnet operations, researchers say.

Computers infected with a virus unknowingly become "zombies" in a botnet which is a network used to send out spam and to mount further attacks on other machines. The zombie army can be controlled remotely, with the botnet creators usually trying to build the largest possible botnet of compromised computers to rent out to gangs for as little as $100 for a couple of hours.

But researchers at antivirus company F-Secure have reported seeing these large networks being broken down into smaller groups of compromised computers because the creation of large botnets is not creating as much revenue for such cybercriminals.
