GopherTCP Listener

Overview#

GopherTCP is an external listener designed for the Gopher agent type. It registers TCP endpoints for lightweight, Go-based agents that target Linux systems.

Characteristics#

Creating a GopherTCP Listener#

1. Open the Listeners tab
2. Click Create
3. Select GopherTCP
4. Configure:
   • Name — Unique name (e.g., gopher-main)
   • Bind Host — Interface to listen on
   • Bind Port — TCP port
   • Agent Address — The address agents use to connect
5. Click Start

Gopher vs. Beacon#

Gopher is designed as a lightweight alternative to Beacon for Linux targets. It supports multiple listener connections simultaneously (multi_listeners: true), meaning a single Gopher agent can connect to multiple GopherTCP listeners for redundancy.

Use Cases#

• Linux-focused engagements — When targets are exclusively Linux
• Smaller payload — When binary size matters (e.g., limited upload bandwidth)
• Redundant C2 — Multiple listener connections provide failover
• Containerized environments — Lightweight agent suitable for container targets
