A great interview with the researchers that implemented aircrack-ptw for Breaking 104 Bit WEP In Less Than 60 Seconds.

When WEP was compromised in 2001, the attack needed more than five million packets to succeed. During the summer of 2004, a hacker named KoreK published a new WEP attack (called chopper) that reduced by an order of magnitude the number of packets requested, letting people crack keys with hundreds of thousands of packets, instead of millions.

Last month, three researchers, Erik Tews, Andrei Pychkine and Ralf-Philipp Weinmann developed a faster attack (based on a cryptanalysis of RC4 by Andreas Klein), that works with ARP packets and just needs 85,000 packets to crack the key with a 95 per cent probablity. This means getting the key in less than two minutes.

Here’s an interview with the three researchers. All three are studying at Darmstadt University of Technology, Germany. Tews, 24, is a Bachelor student; Pyshkin, 27, and Weinman, 29, are PhD students in Professor Johannes Buchmann’s research group.
