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.

An unidentified party leaked over 12TB of Valve's internal builds and unreleased assets, spanning games published on Steam between 2003 and 2013. The trove reportedly includes early versions of Portal 2, Left 4 Dead, CS:GO, and material tied to the canceled F-Stop project and the long-rumored Half-Life 2: Episode 3. Researchers say the data appears to have been exposed via a publicly accessible endpoint, which explains why nothing newer than 2013 has surfaced.

Valve, the studio behind Half-Life and Steam, was founded on August 24, 1996, by former Microsoft engineers Gabe Newell and Mike Harrington. The company released Half-Life in 1998, reshaping first-person shooter design, then launched Steam in 2003, establishing digital game distribution as an industry standard. Today the company celebrates its 30th anniversary with both products still shaping the industry.

Valve LLC was formally registered on August 24, 1996, by two ex-Microsoft employees, Gabe Newell and Mike Harrington, who left secure jobs to bet on making games. They funded the venture with personal savings, a stock sale, borrowed money, and a deal with publisher Sierra On-Line that gave up 30% of revenue and their intellectual property. That gamble led to Half-Life in 1998 and eventually Steam, which began as a simple patch-delivery tool before becoming the dominant PC gaming storefront.
