A 12TB leak of Valve's data has just gone out. No, it has no user data. Your password and other personal information are all safe.
What the leak did give us however was a decade worth of older builds of some of Valve's games ranging from 2003 to 2013. Why does it stop at 2013? Because that's the year "SteamPipe" was implemented, which is Steam's content distribution system, which replaced the old system (known as "Steam2") that year, and it still continues to use that system today.
A longtime Valve dataminer known as Gabe Follower posted on X that early version of Portal 2, Left 4 Dead, Counter-Strike: Global Offense, F-STOP (a codename for an unreleased prequel to the original Portal), and suggesting that Half-Life 2: Episode 3 was found in the files.
Quote From Gabe Follower Someone leaked 12 TB of Valve's internal builds and game assets from 2003 to 2013. This includes early versions of Portal 2, Left 4 Dead, CS:GO, F-Stop and potentially EP3. The community is still researching everything, so the next few days might be insane... There's a Weaponizer from the early HL2 EP3.
Gabe Follower went on the clarify quickly ahead of time that no hacking was involved, and all of the content was found on a publicly accessible endpoint.
Quote From Gabe Follower No hacking involved, just verified that everything in Steam2 Teraleak was obtained via a publicly accessable endpoint. It's Valve's fault...
A few hours later, he shared a screenshot of what appears to be an early development build of Portal 2 featuring portals that are perfect circles instead of the oval shape from the final builds of both games.
Quote From Gabe Follower cursed circular portal doesn't exist, it can't hurt you
cursed circular portal:
Spanish Valve streamer and analyst, Scolcer also shared his thoughts on similar findings.

Quote From Scolcer There was no hack. This is 100% Valve's fault.
The Steam leak came from a site that was completely publicly accessible. It was there for anyone to download. No passwords. Nothing. Hidden in plain sight, but with no protection whatsoever.
This is why it only covers the period from Steam's inception until 2013, when they switched to the new storage system.
This 13-terabyte leak also contains a large amount of third-party content (files/betas of other games that were on Steam before 2013), which means it's a VERY DANGEROUS situation for everyone. Be very careful.
Quote From Scolcer 12 terabytes of Valve data dating from 2003 to 2013 have just been leaked. These data were "hidden" in a public repository. This is Valve's complete repository. This is huge; it could even contain prototypes of Episode 3. Never-before-seen beta content might also be included.
The attached image is the start screen of a 2009 version of Portal 2. The community has already begun investigating these 12 terabytes of data.
All of this is just coming to light. We will continue to provide updates.
Scolcer also shared a slow motion feature and an adhesive gel that would've allowed players to walk on walls and ceilings in Portal 2.
Quote From Scolcer Abilities cut from the Portal 2 beta:
-Adhesive Gel
-Slow Motion
-The Weaponizer from Half-Life 2: Episode 3 was likely used as a placeholder for the Paint Gun
Since then, several tweets and videos have gone up regarding early development builds of Portal 2, and the significant overhaul the game has received over time.
