## What it is
LimeRAT is a remote administration tool (RAT) for Windows written in Visual Basic .NET, providing remote desktop, file management, keylogging, and other client-server control features. It also includes offensive modules such as ransomware, a Monero miner, DDoS, and credential/crypto stealers, and is explicitly framed as educational for understanding .NET malware behavior.

## Use cases
- study how .NET RAT malware works
- learn remote administration tool architecture
- understand AES-encrypted C2 communication
- analyze malware plugin systems
- research AV evasion and persistence techniques
- examine ransomware and screenlocker implementations

## When to choose
- you are a security researcher studying .NET malware behavior
- you want to learn how RAT client-server communication and plugin systems are built
- you need a reference for malware analysis or defense research in a lab environment

## When to avoid
- you need a legitimate remote administration or IT management tool for real machines
- you want maintained, supported software - the project is outdated and archived
- you cannot legally or ethically operate offensive tooling in your jurisdiction
- you need anything other than Windows/.NET Framework 2.0-4.0 targets
