Ubisoft has made PC downloads via its Uplay digital service unavailable while it fixes an exploit that allowed users to download games for free.
Users were reportedly able to download games without paying for them using a small executable file that, when run, tricks the Uplay program into thinking the user owns games which they do not.
The exploit came to light earlier today after it emerged that players could use the exploit to download Far Cry 3: Blood Dragon - weeks ahead of launch.
Weighing in at 3051mb, the as yet unreleased Far Cry 3 spin-off is reportedly in a fully playable state and only available through use of the hack.
Ubisoft has said it's "aware of the issue and are working to resolve it quickly", in a statement to Polygon.
"No personal information was compromised," verified a spokesperson. "Uplay's PC download service will be unavailable until the problem is fixed however all other Uplay services remain available."
