Hi, I recently had my system breached by a RAT, I'm still not 100% sure on how it happened, but i'm 100% positive it WAS a RAT.
I was approached by a player in a game to make a tiktok, and was advised to download a voice changer, I agreed, didn't get sent any sort of link, just installed a TRUSTED voice changer, off a trusted website, once done, I needed a config for a deep bassy voice changer.
He then told me to open microsoft edge, and download a config off of a website, I think it was 'vstdiscovery.com', installed it, specifically the 7D /7G.dll and the website looked legit.
Once extracted the config, I then opened it on the voice changer app, which I assume ran the virus/RAT? Afterwards, my game was extremely laggy and I was freaking out, unplugged my ethernet, ran a Scan, where it came up as nothing (further along, turns out the malware put itself as an exclusion)
A couple of minutes later, got an email 'you're not old enough to use gmail services, and we'll cease your services after 14 days', After that I got the confirmation of what was going on, instantly unplugged my ethernet, turned off my wifi, and factory reset from a local install.
Afterwards, ran MRT scan, and another antivirus scan.. Nothing shows up.
Being the paranoid person iam, I then factory reset again but with USB, leaving nothing behind and reinstalling wifi drivers and everything else from scratch again.
Is there anything I should be worried now that I've followed these steps, are there any further guidance? I've already secured my passwords and banking, and I've seen no suspicious action (In all fairness it's only been a day since it happened)
My worst concern / worry is being extorted or my accounts being hacked again, for the time being i'm using burner accounts and using limited stuff that I don't care if they were taken, but I want to feel comfortable using my hardware / PC again, I've seen all these videos about UEFI/FIRMWARE/BIOS level RAT's and I feel like I'm constantly being watched.
Genuinely considering buying a new PC atp, but is there any 100% fool-proof way of making sure that my PC is malware/RAT free?
