Avasts on-line forum was breached on Monday and the hackers stole usernames and nicknames, email addresses and encrypted passwords.


Avast took the forums off-line. The attack affected less than 400,000 of Avast’s 200 million users.

Leaked passwords where hashed: the password “Rover”, for example, run through the SHA-1 algorithm is “ac54ed2d6c6c938bb66c63c5d0282e9332eed72c.”

Once the forums return to on-line, users will be instructed to change their passwords.
