Cyber-crime just doesn't pay like it used to. Security researchers say the cost of criminal services such as distributed denial of service, or DDoS, attacks has dropped in recent months. The reason? Market economics.
Criminals have gotten better at hacking into unsuspecting computers and linking them together into so-called botnet networks, which can then be centrally controlled. Botnets are used to send spam, steal passwords, and sometimes to launch DDoS attacks, which flood victims' servers with unwanted information.
