Havoc payload generation
Havoc > payload gen --format exe --listener HTTPS
Generates a Havoc payload (demon) in EXE format that will connect to the HTTPS listener configured on the C2 server.
When the Havoc team already has an active HTTPS listener and you need the binary for the delivery phase (phishing or exploitation). Havoc allows compiling the demon in x64 or x86 and choosing architecture based on the target.
If you need execution without touching disk (reflective DLL), Havoc offers injecting the payload in stages or from memory. For very specific payloads with exotic architectures, consider Sliver or Mythic.
