Joris Evers, CNET News.com, reports on the most serious security threat on the Internet, the new-style zombies. Command-and-control centers of hijacked computers (zombies) are moving from Internet Relay Chat (IRC) to new Web-based technologies. Zombies are networked into botnets. These networks are put "to work mounting denial-of-service attacks against online businesses in extortion schemes; hosting faked Web sites used in phishing scams; and relaying spam."
Evers describes the mediums and ongoing efforts to find and block these command centers in his article, Zombies try to blend in with the crowd.
"As new command-and-control mediums emerge, the good guys will adapt their containment and investigatory techniques," says Adam Meyers, a security expert at consulting firm SRA International.
