The makers of Grand Theft Auto VI have filed two Digital Millennium Copyright Act (DMCA) subpoenas targeting Microsoft and Discord in the quest to unmask the leaker known as Cyberleek, who has been posting gameplay footage of the unreleased video game.
Take-Two Interactive Software Inc., the parent company of Rockstar Games, filed two subpoenas on Aug. 20 in the Southern District Court of New York, as first reported by Kotaku. The subpoenas specifically cite "stolen content," which confirms what many gamers have suspected all along — at least some of the gameplay videos and maps posted by Cyberleek are legitimate.
The supbeaonas request specific information "to identify the user or users responsible for posting Take-Two’s copyrighted content online," and the filings name specific Discord users, Discord servers, and GitHub repositories.
One of the subpoenas includes a copy of a take-down request sent to Discord, which states: "The reported post contains unauthorized, leaked gameplay footage from the unreleased game Grand Theft Auto VI. This material reproduces our Client's copyrighted, unreleased game assets and was published and distributed without any authorization from the copyright holder. The content is presented as genuine leaked Grand Theft Auto VI gameplay from Take-Two Interactive Software, Inc., and its distribution constitutes unauthorized reproduction and public disclosure of our Client's copyrighted work."
Cyberleek has been posting a steady drip of leaked gameplay videos, which have spread widely on X, Reddit, and file-sharing platforms. (Mashable is not posting any of the leaked content.) The leaks came about a week before Netflix was due to stream an exclusive "extended look" at GTA 6, and Rockstar's promotional plans have been completely overshadowed by the anonymous leakers.
The filing goes on to name specific Discord users and account IDs associated with the leaker, including "CYBERLEEK" and "CINEMATICROCKSTAR," as well as Discord servers hosting the leaked material.
The subpoena requests "All identifying information associated with all user accounts that are/were members of the Discord community servers and channels listed below during the time period from June 1, 2026, to present. For each returned account, provide the following: backend server metadata or telemetry records, original message logs, IP access logs, email addresses, phone numbers, connected accounts, registration timestamps, linked connections (Google/Xbox/etc.), and any associated device identifiers (MachineGuid/MSA)."
Take-Two also subpoenaed Microsoft, the parent company of GitHub. In that filing, Take-Two also demands that GitHub remove "leaked content" on a specific GitHub repository.
"The entire repository must be completely disabled, there are no remedies to rectify this clear case of infringement," one of the exhibits in the filing states.
As of this writing, the GitHub repository named in the takedown request is still online; it's unclear if that repository is directly associated with the leaker, who has been primarily communicating through a website and Telegram.
The first Cyberleek videos appeared online on Aug. 18, and since then, the leaker has released six gameplay videos and three previews that appear to show the game's map. Grand Theft Auto VI is one of the most highly anticipated video games in history, and after numerous delays and a decade-long development process, gamers are desperate for any information about the upcoming title, which is scheduled for release on Nov. 19.
For now, the identity of Cyberleek is unknown, but the individual (or group) has been promoting a memecoin along with the leaked videos, encouraging people to purchase the coin to vote on what material should be released next. One of the most recent leaks shows the character shooting the word "LEEK" onto a wall, suggesting that the leaker may have a playable version of the game, which would be a nightmare scenario for Rockstar.
Cyberleek has threatened to continue posting leaked footage, and the leaker's website includes a manifesto and list of grievances against video game companies.
Mashable has contacted Rockstar Games and Take-Two Interactive Software Inc. repeatedly with questions about the leaks, and we'll update this story if either company responds.
