[It is safe to play again] The Source Code Leaks megathread

[Fox]

Since the news is kind of a big deal, let's center all discussions here. Existing threads about this can and will be fused there.

Update : official answer directly received, pointing to it now

F.A.Q

What exactly happened ?
The source code for TF2 and CS:GO was apparently leaked to the public. For TF2, the codebase seems to be dated around the time of Jungle Inferno's release.

UPDATE 4 : Official word on the Team Fortress side of things (thanks to sleep for pointing it out) :

Regarding today's reported leak of code, specifically as it pertains to TF2: This also appears to be related to code depots released to partners in late 2017, and originally leaked in 2018.

From our review, we have not found any reason for TF2 players to be alarmed or avoid the current builds (as always, playing on the official servers is recommended for greatest security).

We will continue to investigate the situation and will update news outlets and players if we find anything to prove otherwise. In the meantime, if anyone has more information about the leak, the Valve security page (next tweet) describes how best to report that information.

Does Valve know about this yet ?
UPDATE : They do, and have reviewed it. Source.

How will it impact TF2 ?
UPDATE 4 : No impact foreseen as per official statement above.

I have important informations about the leak !
Refer to this page for contacting Valve about security matters.

Is it safe to play now ?
Yes.

How about the posts showcasing RCEs affecting TF2 clients ?
There is a high chance they were fake.

Will having the game installed be risky ?
No, see official answer above.

Do you have any other information ?
None, I'm afraid. Either I genuinely don't know, or I am not allowed to share it, which is functionally identical for you guys. If there's news, I'll add it to the FAQ.

I have another question
There's not much more I can answer, but if the question is frequent enough and I get an official answer, I'll add it.

F.A.Q. updated as of 23/4, may be updated without notice.
If you have updates, contact me directly through my profile comments : I'll be probably be darting left and right across hubs.

The "exploit' code was found in the Source SDK 2013. And that particular code was patched in this update: https://wiki.teamfortress.com/wiki/June_16,_2017_Patch

This is the exploit details and the guy who found it: https://www.oneupsecurity.com/research/remote-code-execution-in-source-games/

Yeah but my man my main question is, should I be worried, given what Ive stated?

No you should not be worried. The exploit will not work in any version of TF2 since mid 2017. Even if they know the exploit and how to do it, it has since been patched and will not work.

I would not risk it

[пенис]

[Swag man Ethanator]

can they only get in from game servers? asking cause i have a few items in the workshop, and i would hate it if they somehow Hijack and my mods and use it to spread their hacks.
