Rumor: Steam Source Code Was Possibly Just Leaked

As of this moment, Valve is currently trending on twitter because the source code for two of their games has been apparently leaked. Hackers are now reportedly able to infect users PCs with malware through Remote Code Execution. The games affected currently are both TF2 and CSGO but reportedly playing other Valve multiplayer games can put users at risk. Originally reported by Steam Database The code dating back to 2018 and 2019 was just leaked to the public today. Here is everything we know so far regarding the Steam Source code leak.

Further information regarding how serious the situation may be, comes from the account @HeavyUpdateOut who states that users can apparently get a virus from just joining a server. According to an article from PCGAMESN popular TF2 servers Creators.TF and Red Sun have shut down operations and are advising players to stay away until the exploits have been addressed.

Do not launch TF2 under any circumstances, Remote Code Execution exploits have already been found which means you can receive a virus from simply joining a server with a cheater. This is not a drill.

The exploits as told by a Creators.TF mod can apparently allow hackers to access user’s PC files. While others can apparently turn you into an aimbot or delete your entire item inventory by just playing the game. As of this moment, Value has not made any official statements addressing this situation. Until then it is uncertain how serious the leaks are. However, for the time being, we recommend avoiding all Value source code multiplayer games until the issue is addressed. The source code was allegedly leaked to the website 4chan.

Due to the recent source code leak we will be closing our servers for the forseeable future. This is because of the uncertainty surrounding security of our infrastructure, as well as a potential for damage to be caused to your computer.https://t.co/gWcIKRMPdj

Not just the Steam source code has been hacked apparently. It was reported that the Steam client was also hacked but this is still unconfirmed. Also according to a YouTube video posted by someone taking credit for the hack, it can also potentially steal Steam accounts. This is unconfirmed as well but regardless we recommend staying away from the following games until this issue is addressed by Valve; Gmod. CSGO, Team Fortress 2  or any steam game that uses the valve source code. We will continuously watch and update this as it is currently still in development, Stay safe Readers.

Update: According to a recent upload by Valve News Network the source code was allegedly leaked by a former employee. This employee became disgruntled when they had their access removed and restricted and apparently leaked what they had onto 4chan.

Update: The official CS:GO Twitter account has just released the following statement on the current situation.

We have reviewed the leaked code and believe it to be a reposting of a limited CS:GO engine code depot released to partners in late 2017, and originally leaked in 2018. From this review, we have not found any reason for players to be alarmed or avoid the current builds.
