## What it is
NetRipper is a Windows post-exploitation tool that uses API hooking to intercept network traffic, capturing both plain-text and encrypted data before encryption/after decryption. It includes a Metasploit module and is designed for penetration testers with low-privileged access on compromised machines.

## Use cases
- sniff network traffic from applications on a compromised Windows machine
- capture encrypted traffic before encryption from low-privileged user context
- capture credentials from tools like Putty, WinSCP, Outlook, Chrome, Firefox
- post-exploitation data gathering via Metasploit module
- search captured traffic for specific strings like user, pass, config
- analyze network activity of a malicious application

## When to choose
- you are a penetration tester needing to sniff traffic on a fully patched Windows host with low privileges
- you need to capture encrypted traffic before it is encrypted by hooking crypto APIs
- you want Metasploit integration for post-exploitation workflows

## When to avoid
- you need a general-purpose network sniffer like Wireshark or tcpdump
- your target platform is Linux or macOS
- you need actively maintained tooling with recent updates and broad community support

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, networking, reverse-engineering
- domain: security, penetration-testing, windows
- platform: windows, cli
- tags: traffic-sniffing, api-hooking, post-exploitation, metasploit, credential-capture
