[[Introduction]]\n[[People]]\n[[Publications]]

In this project we are investigating different methodologies of misusing peer-to-peer (~P2P) systems to launch ~DDoS attacks against innocent victims that are not part of the ~P2P system. We started by investigating [[BitTorrent|http://www.bittorrent.com/]] and found several vulnerabilities that could lead to such attacks. Our results are published in the paper "~BotTorrent: Misusing ~BitTorrent to Launch ~DDoS Attacks" which appeared in the USENIX 3rd Workshop on Steps Towards Reducing Unwanted Traffic on the Internet ([[SRUTI'07|http://www.usenix.org/events/sruti07/]]).\nWe are continuing to investigate this problem and design enhancements to ~BitTorrent that would illiminate such misuse. This is still an open problem and these types of attacks still occur highlighted lately by the attack on [[Revision3|http://revision3.com/]] (story in slashdot is [[here|http://yro.slashdot.org/article.pl?sid=08/05/29/2026213&from=rss]] and from [[Revision3's website here |http://revision3.com/blog/2008/05/29/inside-the-attack-that-crippled-revision3]]).
