AsyncRAT is an open-source Remote Access Tool (RAT) written in C# that lets an operator remotely monitor and control Windows client machines over an encrypted TCP connection. It includes a plugin system, terminal access, screen viewing/recording, SFTP file transfer, keylogging, password recovery, and a configurable server with a binary builder and obfuscator.

Use cases

• remotely administer Windows machines over an encrypted connection
• view and record a remote client's screen
• transfer files to and from remote clients via SFTP
• manage multiple clients through a terminal and chat window
• build and obfuscate custom client binaries
• extend remote functionality with a plugin system

When to choose

• you are a security researcher studying RAT behavior or malware analysis
• you need a self-hosted remote administration tool for Windows machines you own or are authorized to test
• you want an extensible C# codebase to learn how remote access tools are built

When to avoid

• you need a legitimate enterprise remote-desktop or MDM solution for production IT
• you lack explicit authorization to access the target systems - unauthorized use is illegal
• you need cross-platform client support beyond Windows
• you want a maintained tool with regular security updates
