Yahoo! Inc. said today that a security breach on its site exposed 450,000 user names and passwords for accounts at Yahoo and other Internet services such as Microsoft Corp.’s Hotmail and AOL Inc.
A file containing login credentials for Yahoo and other accounts was stolen from a Yahoo site featuring user articles, videos and slideshows on July 11, the company said in an e- mailed statement today.
The hackers that posted the information made efforts to mask which Yahoo site the stolen passwords came from, but inadvertently left clues in the file that point to the Yahoo! Voices site as the source of the breach, TrustedSec wrote.
