DDoS Attacks Via DNS Recursion

Posted by ryuzaki0 on from the to-understand-recursion-you-must-understand-recursion dept.

JehCt writes "Associated Press is running a story about how the recursion feature of open DNS servers can be used to launch massive distributed denial of service (DDoS) attacks: 'First detected late last year, the new attacks direct such massive amounts of spurious data against victim computers that even flagship technology companies could not cope.' A thread at WebmasterWorld explains, 'To make a long story short, having a DNS server that allows recursion for the Internet is like running an open SMTP relay.'"
