Yahoo investigating reported mass password breach

Posted: Updated:

Hackers posted online what they say is login information for more than 450,000 Yahoo users.

The group behind it said the data was released as a wake-up call and warned Yahoo to take a closer look at its current security coverage.

Yahoo apologized and urged users to change their passwords regularly.  They added less than 5%of the breached accounts had valid passwords.
