Had to Happen Eventually: WPA Vulnerability Exposed
A researcher says he’s exposed a vulnerability in WPA security:
“Cryptographic expert Erik Tews will appear at PacSec security conference in Tokyo next week with his presentation, ‘Gone in 900 seconds: Some Crypto issues with WPA.’ There, Tews is expected to show off his discoveries in TKIP (Temporal Key Integrity Protocol) cracking, that allow WPA to be broken in a brief 12-15 minute window.
“TKIP itself is not really crackable, since it is a Per-Packet Key, but once it is initialized, the Pairwise Master Key (PMK) can be obtained. From there, the conventional method of breaking in involved a brute force dictionary attack, or a long process of elimination by trying millions of options.
