WPA-PSK Cracking As a Service

kdawson — Tue, 08 Dec 2009 00:31:00 +0000

An anonymous reader writes "Moxie Marlinspike, a security researcher well known for his SSL/TLS attacks, today launched a cloud-based WPA cracking service, where for $34 you can test the security of your WPA password. The WPA Cracker Web site states: 'WPA-PSK networks are vulnerable to dictionary attacks, but running a respectable-sized dictionary over a WPA network handshake can take days or weeks. WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords. While this job would take over 5 days on a contemporary dual-core PC, on our cluster it takes an average of 20 minutes.'"

Open Source Attempt To Crack GSM Encryption

Lexta writes with an interesting tidbit from IEEE Spectrum: "'Karsten Nohl, chief research scientist with H4RDW4RE, a Sunnyvale, Calif.-based security research firm, is mounting what could be the most ambitious attempt yet to compromise the GSM phone system.' The intended approach is to create an open source project to spread the computation of a giant look-up table across more than 80 machines. Interestingly, they've openly stated that nVidia's CUDA technology will be used to execute parallel elements of the problem on GPUs as well."

The Voynich Manuscript May Have Been Decoded

MBCook sends word on a possible solution to the mystery of the Voynich Manuscript, which we last visited nearly 6 years ago. "The Voynich Manuscript has confounded attempts to decode it for nearly 100 years. A person named Edith Sherwood, who has previously suggested a possible link to DaVinci, has a new idea: perhaps the text is simply anagrams of Italian words. There are three pages of examples from the herb section of the book, showing the original text, the plaintext Italian words, and the English equivalents. Has someone cracked the code?"
