Warp Pipe Tester
Network tunnel and port forwarding testing utility for validating connectivity and data exfiltration paths.
curl -O https://raw.githubusercontent.com/MHaggis/notes/master/utilities/warp_pipe_tester.py && python3 warp_pipe_tester.py ⚠ The Problem
Testing network tunnels, port forwards, and data exfiltration paths requires manual setup and validation. Defenders need to understand which tunneling methods work in their environment, and red teams need to quickly identify viable exfiltration channels.
✓ The Solution
Warp Pipe Tester automates the testing of various tunneling and port forwarding techniques, including SSH tunnels, reverse tunnels, SOCKS proxies, and custom protocols. It validates connectivity and measures throughput for each method.
⚡ Impact
Helps security teams understand their network egress controls and identify potential data exfiltration paths. Used by both attackers to find working tunnels and defenders to validate network security controls.
