Merlin is a cross-platform post-exploitation Command & Control server and agent written in Go. The Merlin server is a self-contained command line program that requires no installation. You just simply download it and run it. The command-line interface only works great if it will be used by a single operator at a time. The Merlin agent can be controlled through Mythic, which features a web-based user interface that enables multiplayer support, and a slew of other features inherent to the project.

Features

  • Supported C2 Protocols: http/1.1 clear-text, http/1.1 over TLS, HTTP/2, HTTP/2 clear-text (h2c), http/3 (http/2 over QUIC)
  • Server and Agent: Windows, Linux, macOS (Darwin), MIPS, ARM or anything Go can natively build
  • Execute .NET assemblies in-process with invoke-assembly or in a sacrificial process with execute-assembly
  • Execute arbitrary Windows executables (PE) in a sacrificial process with execute-pe
  • Various shellcode execution techniques: CreateThread, CreateRemoteThread, RtlCreateUserThread, QueueUserAPC
  • OPAQUE Asymmetric Password Authenticated Key Exchange (PAKE)
