Crystal Kit - Mythic Xenon

Rasta Mouse's Crystal Kit with a small tweak for compatibility with Mythic Xenon Agent.

Crystal Kit

This repo is a technical and social experiment to explore whether replacing Cobalt Strike's evasion primitives (Sleepmask/BeaconGate) with a Crystal Palace PICO is feasible (or even desirable) for advanced evasion scenarios.

Usage

1. Disable the sleepmask and stage obfuscations in Malleable C2.

stage {
    set sleep_mask "false";
    set cleanup "true";
    transform-obfuscate { }
}

post-ex {
    set cleanup "true";
    set smartinject "true";
}

2. Copy crystalpalace.jar to your Cobalt Strike client directory.
3. Load crystalkit.cna.

Notes

• Tested on Cobalt Strike 4.12.
• Can work with any post-ex DLL capability.
