According to a recent report from Arbor Networks, hackers began launching IPv6 DDoS attacks for the first time last year.

"Even though 2011 was the first year when IPv6 DDoS attacks were recorded, such incidents remain rare because they are not economically relevant for Internet criminals, said Bill Cerveny, a senior software quality assurance engineer at Arbor," writes Computerworld's Lucian Constantin.

"'We see IPv6 attacks as an emerging threat,' said Neal Quinn, vice president of operations at DDoS mitigation vendor Prolexic, in a phone interview," Constantin writes. "Quinn believes that the current IPv6 DDoS attacks are most likely tests performed by malware writers who want to be prepared when large Internet service providers will start switching their subscribers to IPv6."
