First news of the day:
— 2Eggs - "better to be safe than sorry" (@2Eggsss) April 22, 2020
The Source Code of @TeamFortress and @CSGO from 2017 (~Op Hydra) has been leaked and published onto the internet for everyone to see, use and download.
Yikes!
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.

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.
