A thread on Reddit’s /r/gta5 section has reported multiple Rockstar Games Social Club accounts have been compromised with tales of email and password changes and lengthy processes with Rockstar Customer Support to resolve the problem. A link within the discussion highlights 100’s of leaked accounts suggesting there may be more than luck involved with how the account details have been made accessible.
Rockstar however confirmed to Kotaku Australia that its systems have not been compromised but that access is being achieved through other means beyond their control;
However, it appears that attempts have been made to access user accounts using email and password combinations from an unaffiliated, compromised website or database elsewhere on the internet. For the accounts affected, we are in the process of reverting those accounts back to their original owners. As a reminder, it is a good policy to ensure that the Rockstar Games Social Club account username and password is not shared across multiple websites on the internet.
The overall suggestion is to use unique login details for each site with services like LastPass helping to ensure you don’t use easy to guess passwords or use duplicate information across multiple sites. Doing so will reduce the likelihood of a compromised account on online services.
