An anonymous reader writes "Some 450,000 email addresses and associated unencrypted passwords have been dumped online by the hacking collective 'D33Ds Company' following the compromise of a Yahoo subdomain. The attackers said that they managed to access the subdomain by leveraging a union-based SQL injection attack, which made the site return more information that it should have. According to Ars Technica, the dump also includes over 2,700 database table or column names and 298 MySQL variables retrieved during the attack."

The information has since been removed but it wasn't just credentials for Yahoo, but also Gmail, AOL, Comcast, Hotmail, MSN, SBC Global, BellSouth, Verizon and Live.com as well."
