"A team of cryptologists at Luxembourg university have made substantial theoretical progress with attacks on the AES-192 and AES-256 encryption standards. In their paper, scientists Alex Biryukov and Dmitry Khovratovich describe how to crack an AES-256 key with a time complexity of 2^123 and an AES-192 key with a time complexity of 2^176 under certain circumstances. Due to some special characteristics, however, the attacks have no practical relevance for the security of AES-encrypted data." - imabonehead from Bookmarklet

such a Luxembourgian names these guys have... :) - A.T.
