Amazon Cloud Can Help Hack WiFi Networks

Tuesday Jan 11th 2011 by Staff

A German researcher claims he can crack WPA passwords in about six minutes with a brute force attack that relies on Amazon EC2.

Reuters: German security researcher Thomas Roth says he has written a program that can crack the WPA encryption that protects many WiFi networks in about six minutes with help from Amazon's EC2 cloud services. He plans to release his software and explain his methods at the Black Hat conference.

Roth's method tests 400,000 potential passwords per second using cloud-based infrastructure that costs $0.28 per minute.

Amazon spokesman Drew Herdener responded to the announcement by noting, "Testing is an excellent use of AWS [Amazon Web Services], however, it is a violation of our acceptable use policy to use our services to compromise the security of a network without authorization."
