Basic PoC script to vaccinate Windows endpoints against paranoid malware
This repository contains:
- Scripts for vaccination, as discussed demonstrated in the talk
- One of IRONGATE's components source code (warning, malware!) to demonstrate the inner mechanisms of paranoid malware
- A list of the tested malware
The core of the repository will create artifacts simulating an environment trying to mimic indicators of:
- Virtual machines and emulators
- Sandbox
- Security products
- Forensic tools
- The malware iteslf (AKA infection markers)
Feel free to contribute more artifacts.
HOWTO
Execute vaccination_manager.py on the machine you wish to protect with the following flags:
-s create only static artifacts
-d create only dynamic artifacts, the script needs to keep running if you want it to protect the endpoint
-a create both static and dynamic indicators, the script needs to keep running if you want it to protect the endpoint
-w update the artifact list from an online repository, if you wish to use it install python's requests module
Note that if you wish to test the dynamic vaccination module you'll need to either re-run on each reboot.

Andromeda\Gamarue Bot
periodically checks if any of the running processes are in a hardcoded anlysis related blacklist, if none are found it will create malicious child process - otherwise it will keep running and test later again which processes are running. 31f81b5e6854dfee0739c1f8266668622b13f36a5499d98809fcc04603ee7152
