LONDON (AP) — Yahoo Inc. said Thursday it is investigating reports of a security breach that may have exposed nearly half a million users’ email addresses and passwords.
The company said it was looking into “claims of a compromise of Yahoo! user IDs” but did not disclose the size of the reported breach or how it may have happened. Yahoo’s Head of U.K. Consumer PR Caroline MacLeod-Smith said that she couldn’t immediately provide any more detail on the breach “as we are still investigating it.”
Technology news websites including CNET, Ars Technica, and Mashable cited hackers calling themselves the D33D Company as claiming responsibility for the attack, adding that data posted to the group’s website carried more than 453,000 login credentials from an unidentified Yahoo subdomain.
