According to torrent news site TorrentFreak, the studio was one of the first to attempt to downloaded a file posing as an Xbox 360 Black Ops full game torrent on a popular P2P site.
The site runs an image - which you can see here - showing 'external.treyarch.com' downloading the torrent file.
The site admits that 'it's impossible to confirm its authenticity' - and Treyarch is unlikely to confirm its involvement.
Indeed, if you've attempted to download the Black Ops torrent mentioned, the developer may already have you in their sights. Sleep tight.
For the rest of you, avoid.
If you're sensible enough to wait for the retail release, Black Ops hits stores on November 9 for PS3, Xbox 360 and PC.
