A 12-terabyte trove of Steam2-era content dating from 2003 to 2013 has appeared online, reportedly containing nearly every uploaded build for that decade, including cut Portal 2 assets, Half-Life 2: Episode 3 files, and beta versions of Left 4 Dead 2, CS:GO, Spore, and Dragon Age: Origins. Researchers say the material came from an unsecured public API tied to Valve's old distribution system, which was replaced by SteamPipe in 2013 and left this data exposed without any password protection.

A 12-terabyte archive of data from Valve's old Steam2 content servers, used between 2003 and 2013, has surfaced via BitTorrent in an incident dubbed the 'Teraleak.' The trove reportedly contains unreleased builds and prototypes from Valve and other developers, including early Portal 2 prototypes and a Sonic the Hedgehog 4 build, and appears to have been assembled from publicly accessible endpoints rather than a hack.

A massive 12TB torrent dubbed the Steam 'teraleak' has surfaced online, containing thousands of game depots from Valve's old Steam2 content distribution system used between 2003 and 2013. The trove includes public release builds as well as previously unseen prototype, pre-release, and playtest versions of games from Valve and third-party publishers. Data miner Gabe Follower says the material was pulled from a publicly accessible API endpoint, suggesting the exposure originated from Valve's own systems rather than a hack.
