Speakeasy is a Windows user-mode and kernel-mode emulation framework that runs binaries, drivers, and shellcode inside a modeled Windows runtime instead of a full VM. It can be driven via a CLI for fast triage or embedded as a Python library, producing structured JSON reports of API, filesystem, registry, and network activity.

Use cases

  • emulate windows malware samples without a vm
  • analyze malicious shellcode behavior safely
  • triage suspicious dlls and drivers quickly
  • trace api calls made by a windows binary
  • generate reports of malware execution
  • reverse engineer windows kernel rootkit drivers

When to choose

  • you need fast, scriptable windows binary emulation without spinning up a VM
  • you want structured JSON reports of API, filesystem, registry, and network activity
  • you want to embed emulation into a Python analysis pipeline
  • you need to emulate both user-mode binaries and kernel drivers

When to avoid

  • you need full fidelity execution of complex software that depends on unmodeled Windows internals
  • you need dynamic analysis of non-Windows binaries
  • you want a turnkey sandbox with a GUI rather than a programmable framework
