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
