Flex the network
Once a victim is compromised through a Tentacle agent, relaying and proxying will help you dig deeper.
Agents can relay callbacks from other agents, helping you cross over network boundaries and maintain control even over systems disconnected from the Internet.
The Tentacle server can also proxy (SOCKS) network connections through any agent, allowing direct access into the target infrastructure.
How it works
Tentacle is distributed as a single executable file — no installers, no dependencies, no admin privileges required. Just run it, and your command center is ready. By default, Tentacle launches a local web interface on ports 8080 (HTTP) and 8443 (HTTPS), fully configurable via command-line arguments. All operations, from infrastructure setup to payload management, are performed through this embedded web UI. A lightweight SQLite database is created alongside the binary to persist all session and configuration data.
