Xzbot: Notes, honeypot, and exploit demo for the xz backdoor (CVE-2024-3094)

> Not very sophisticated, but it'll work.
Unfortunately, we live in a world with closed-servers and appliances - being able as a customer or pen tester rule out certain class of security issues without having the source/insights available is usually desirable.

I am not an expert, but this is what I would start by doing. Ideally, if you can read javascript, try and understand what the tampermonkey script does. If you still have script, you could try analysing it with tools such as loki. Even if loki doesnt match it you could compute the sha256 signature and look it up on valhalla.
