## What it is
A collection of Python proof-of-concept code and research notes documenting a hidden backdoor listening on TCP port 32764 in Linksys, Netgear, Cisco, and other SerComm-based routers. It includes a detection/exploitation PoC and a community-maintained list of affected devices and firmware versions.

## Use cases
- check if my router has the TCP 32764 backdoor
- scan a router for the SerComm hidden backdoor
- research router firmware backdoors
- test whether a firewall rule blocks port 32764
- find which router models are affected by the 32764 backdoor

## When to choose
- auditing consumer routers for the SerComm TCP-32764 backdoor
- security research on embedded device backdoors
- verifying mitigation steps after discovering the backdoor on your network

## When to avoid
- general-purpose network scanning or penetration testing
- routers not based on SerComm firmware
- actively maintained tooling - the repository is no longer updated

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: security, penetration-testing, networking, developer-tools
- domain: security, networking, hardware, reverse-engineering
- platform: python, windows, cross-platform
- tags: router-backdoor, tcp-32764, sercomm, vulnerability-research, poc, linksys, netgear, firmware, linux, macos
