Yahoo! Inc. (YHOO), operator of the biggest U.S. Web portal, said that as many as 450,000 user names and passwords were stolen from one of its sites.

Hackers took a file on July 11 containing login credentials for Yahoo and other accounts, such as Google Inc. (GOOG)’s Gmail, Microsoft Corp. (MSFT)’s Hotmail and AOL Inc. (AOL), from a Yahoo site featuring user articles, videos and slideshows, the company said in an e-mailed statement today.

Yahoo joins a growing list of Internet companies such as LinkedIn Corp. (LNKD), CBS Corp. (CBS)’s music site and EHarmony Inc. that have recently had user information compromised.
