Not the greatest news for Steam users this week as a security lapse in the ever popular service allowed for some accounts to be hijacked simply by a hacker having access to a username.
This loophole — which Valve have stated was a ‘bug’ in the system — has now been patched up and affected users contacted to update account credentials.
Valve also issued the following statement:
To protect users, we are resetting passwords on accounts with suspicious password changes during that period or may have otherwise been affected. Relevant users will receive an email with a new password. Once that email is received, it is recommended that users login to their account via the Steam client and set a new password.
Please note that while an account password was potentially modified during this period the password itself was not revealed. Also, if Steam Guard was enabled, the account was protected from unauthorised logins even if the password was modified.
We apologise for any inconvenience.
Valve has a little program called Steam Guard which prevents against these issues, all users of the service are recommended (like anything on PC) to take measures to help prevent breaches in security.
