The AACS Licensing Authority (AACS LA) just can't catch a break. On May 22nd, Blu-ray and HD DVD titles containing the latest version of AACS (MKB v3) were released. A day later, someone going by the name "BtCB" posted the new processing key (45 5F E1 04 22 CA 29 C4 93 3F 95 05 2B 79 2A B2) on the Freedom to Tinker website. Its still not known how this key was retrieved. However, it has been verified to work by the folks on the Doom 9 forums.

The AACS LA has yet to respond to this. However, at this point, there isn't much they can do besides issue legal threats to websites posting the key. The group must give 90 days notice before revoking the key, giving hackers plenty of time to find a new one.
