9.88 ETH stolen from metamask

I just recently found out I had my ETH drained from my metamask account.

It was irresponsible to leave there and it's pretty devastating.

The transaction.

Hackers Address.

I don't get how it happened. I haven't touched the wallet for months. My seed phrase is stored offline in a dead device. The transaction is not in my activity tab so I assume that means it wasn't done physically on my device. It looks like other people had their funds stolen on the same day as well on November 23rd. What just happened?

**I likely downloaded some malware, my downloads before the hack.

Most likely though, considering others were hacked at the same time, the malware likely had been on my computer for a much longer time and the hacker was waiting to pull many triggers at once.

The 2 sketchy names at the top are canon printer software and they contain digital signatures. Rojo is supplementary software for roblox studio. Node, vscode, Github, and Unity have digital signatures. msys2 and rustup I downloaded to install Rust for programming on my computer, they do not have digital signatures and I do not remember where I downloaded them.

Either the malware was recently injected through msys2, rustup, or Rojo, or it has been in stealth mode on my computer for a very long time.
