GoKawiilMassive 12TB leak exposes decade of Valve's Steam files from 2003-2013
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.
