Winpayloads is a Python 2.7 tool for generating undetectable Windows payloads with extras like UAC bypass, persistence, and PowerShell stagers. It integrates with Metasploit and popular PowerShell post-exploitation scripts and is now primarily distributed via Docker.

Use cases

  • generate undetectable windows payloads for penetration testing
  • bypass antivirus detection on windows targets
  • bypass uac on compromised windows machines
  • add persistence to a payload that survives reboot
  • invoke powershell payloads in memory with a stager
  • spray psexec with stolen hashes across a network
  • create custom shellcode payloads for red team engagements

When to choose

  • you are doing authorized penetration testing or red teaming against Windows targets
  • you need payload generation with AV evasion, UAC bypass, and persistence in one tool
  • you work from Kali Linux and already use Metasploit

When to avoid

  • you need a maintained tool - it runs on deprecated Python 2.7 and development is stale
  • you are not authorized to test the target systems - this is offensive tooling
  • you need modern evasion against current EDR/AV, as detection rates have grown
