The Final Nail in DES's Coffin

Talk by David Hulton

Friday from 2:30 PM - 2:50 PM in Stage C

In 2012 a full break of PEAP/MSCHAPv2 (PPTP VPNs, WPA-Enterprise, etc) was shown by doing a brute-force of the DES keyspace using FPGAs and added support to cloudcracker.com to make this attack accessible to everyone (and not just people with a >$100k FPGA cluster). The talk will also serve to release a new DES cracking service that will provide more of a general purpose interface allowing you to crack most protocols and file formats that use DES assuming you have enough known-plaintext to verify keys. Also, some new attacks that leverage the system to do interesting things will be covered.
