100,000 Gmail accounts put at risk by Yahoo! breach

If the news that the Yahoo! Contributor Network user-generated content site has been breached and more than 450,000 usernames and passwords compromised as a result wasn't bad enough, look behind yesterdays headlines and the situation is revealed to be much, much worse. If you were one of those folk who signed into the Yahoo! Contributor Network with your Gmail or Hotmail credentials, then those accounts are also obviously now compromised.
