## What it is
Hollows Hunter is a Windows command-line tool built on the PE-sieve passive memory scanner that scans running processes for malicious implants such as replaced or implanted PEs, shellcodes, hooks, and in-memory patches, and dumps them for analysis. It supports filtering targets by PID, name, or creation time, continuous scanning via a loop mode, and ETW-based listening.

## Use cases
- scan all running processes for malicious in-memory implants
- detect process hollowing and injected shellcode on Windows
- dump suspicious PE modules from live processes for malware analysis
- continuously monitor a system for memory-based malware
- triage an infected machine during incident response
- filter process scans by PID, name, or creation time

## When to choose
- you need to inspect live Windows process memory for injected code or patched modules
- you want to scan many processes at once rather than a single PID like PE-sieve
- you need to extract implants to disk for offline reverse engineering
- you want a lightweight, scriptable CLI for malware triage

## When to avoid
- you are on Linux or macOS - it is Windows-only
- you need real-time endpoint protection rather than on-demand scanning
- you want a GUI-based forensic suite
- you need to scan memory dumps offline rather than live processes
