I don't want to publish detection results as I'm not convinced it is not helping the bad guys more and in any case if you bought a shiny an expensive product you should take it for a spin. With all this around it should be fairly easy.
It is a reduced and also somewhat extended version of a test case we were using. Let me know or open a PR if something does not work

• You are installing an npm package that has a dependency that got backdoored
• In a malicious preinstall script it downloads and runs a script
• That drops a bunch of backdoors
• Adversary is obvious oldschool reverse shell and opensource tools like Metasploit (and I recommend adding Mythic, but I was too lazy to automate that)

Having realistic test cases for testing security tools is hard to come by

• You don't want to waste time creating a complicated, realistic scenario but if you get detected it is unclear if this is because what you did was obvious or it would get detected in less obvious situations too (legit parent, staged loading etc)
• If things don't you will get push back from providers - "Hey this is just your lab stuff in reality we would have detected it"
• Created a bunch of different versions of reverse shells so you can check how robust the detection is

• include exploits / use any vulnerability
• have novel bypasses
• include anything post exploitation

• Metasploit handlers will die every once in a while so only use

• You will need a test machine(s) where you will be dropping the backdoors (local) and C2 that it will be able to access (remote) local: you will need curl, sed, bash and of course npm. For some backdoors to work you will need python, php. Some of the getto reverse shells will fail because of shell syntax/capability/package difference but it should not break script execution. But really just use the vulnerable box for Linux remote: you will need Metapsloit (and ruby if this does not come with it)

Super simple, but the internet will know your C2 IP:
1, fork the repo and set the C2 IP in the config file
2, clone your fork on the C2 and run setup_and_run_remote.sh
3, clone your fork on all your test machines and run setup_and_run_local.sh
Alternatively you can just clone this one and remember to set all configs without making typos.

There is also a vulnerable Linux VM you can use for testing. Comes with:

• npm installed to run the a backdoored package installation
• kernel version that has a few privilege escalations that have metasploit modules
• docker so you can privilege escalate like you would on any developer machine
• it is in vagrant to help you snapshot/reset to states you might need in testing

• This is just a lab scenario: Nope
• Nobody uses these tools in reality, we do detect malware/miner etc better: Yeah, naaah..
• A reverse shell by itself is not malicious: I recommend you try all the post scripts in Metasploit but don't start with the exploits. You can also manually do some obvious authorized_keys or cron persistance.

• adding Mythic is really worth it and you can work with a proper modern C2 framework
• for macOS there is some pretty cool JXA stuff out there that works
• in some cases EDRs do detect command patterns maybe you want to have other options than wget -> sh and wget -> chmod -> run
• payloads are served from the same IP but I tried to make it easy for you to change that (does not make a difference though)
