The story, "AES proved vulnerable by Microsoft researchers" incorrectly identified the nationality of Katholieke Universiteit Leuven in the lead paragraph. The copy has been changed on the wire. The corrected paragraph should read:

Researchers from Microsoft and the Belgian Katholieke Universiteit Leuven have discovered a way to break the widely used Advanced Encryption Standard (AES), the encryption algorithm used to secure most all online transactions and wireless communications.
