Someone told me about cold boot attack so I'll journal it here too. It's forensics related. To summarize, it is about saving the PC's RAM until it gets erased.
What's interesting is the lower the temperature, the longer the period of time the information is available for.
I found these 2 russian articles interesting. I'd summarize, but I feel it's a bit too much effort now.

https://xakep.ru/2023/01/17/cold-boot-attack/ - this is a recent one that actually explains how to do it with a flash drive. But you need a subscription to access the full article. Maybe I will get it one day.
Also there's an announced game on steam by the same name idk.
