## What it is
icmpsh is a simple reverse ICMP shell tool with a Windows slave (client) written in C and a portable master (server) implemented in C, Perl, or Python. It establishes a command shell over ICMP echo requests, and unlike similar tools it does not require administrative privileges on the target machine.

## Use cases
- get a reverse shell when TCP egress is firewalled
- tunnel shell traffic over ICMP echo requests
- run a reverse shell on Windows without admin privileges
- pivot out of a DMZ machine with strict egress filtering
- demonstrate ICMP-based covert channel risks in pentest reports

## When to choose
- the target is Windows and you need a shell without admin rights
- egress filtering blocks TCP/UDP but allows ICMP
- you want a lightweight, dependency-free C2 channel for a pentest

## When to avoid
- the target is not Windows (slave only supports win32)
- you need encrypted or authenticated C2 traffic
- you need a maintained tool with active development and a license

## Facets
- artifact type: cli-tool
