Valve removes free horror game from Steam after players discover it contains malware that steals your data.
A game on Steam was found to contain malware that would steal login credentials, crypto and other stuff.
In short, a malicious attacker gained access to the developer's account for a small game called Rodent Race, replaced everything with a new game, made it free, and hid malware in a file called UnityPlayer.dll. He then proceeded to steal the information from anyone who downloaded the game. Apparently, and from what I've read, this was possible because Steam doesn't verify update files.
Here's a video that goes into more detail;

The game, now called Beyond The Dark, was removed from the store, though some keys still appear to be circulating from before the hijack. If you downloaded the game, you should consider updating your passwords (emails, crypto wallets, and other sensitive stuff) and run some anti-malware.
