Telecommunications and Internet service provider Level 3 Communications of Colorado spotted anomalous traffic on its backbone starting in mid-June almost as beta runs of attacks that were carried out Aug. 10-12 against a handful of targets in the gaming and web hosting industries. There are 1.1 million Portmapper servers accessible online, and those open servers can be abused to similar effect as NTP servers were two years ago in amplification attacks.Read more of this story at Slashdot.
