'In an award-winning paper last week, academics said they discovered a way to abuse the TCP protocol, firewalls, and other network middleboxes to launch giant distributed denial of service (DDoS) attacks against any target on the internet.

Authored by computer scientists from the University of Maryland and the University of Colorado Boulder, the research is the first of its kind to describe a method to carry out DDoS reflective amplification attacks via the TCP protocol, previously thought to be unusable for such operations. Making matters worse, researchers said the amplification factor for these TCP-based attacks is also far larger than UDP protocols, making TCP protocol abuse one of the most dangerous forms of carrying out a DDoS attack known to date and very likely to be abused in the future.'
