Another gem from Sysinternals, AutoRuns shows you everything that runs at system startup. Malware loves to persist by hooking into startup tasks, scheduled tasks, services, drivers—you name it.
AutoRuns gives you visibility and control. You can disable or remove suspicious entries with a click. It’s also handy for cleaning up after malware removal.
12. Fiddler
Fiddler is a web debugging proxy that lets you inspect HTTP and HTTPS traffic. It’s perfect for seeing how malware communicates with the web—be it fetching payloads or sending stolen data.
You can modify requests/responses, simulate attacks, or replay sessions. If malware uses web APIs or drops from a malicious domain, Fiddler catches it in the act.
13. HxD
HxD is a simple yet powerful hex editor. It allows you to dig into raw binary data, making it essential for static analysis. Want to peek into the file header? Change a few bytes? HxD’s got your back.
It’s light, fast, and doesn’t try to do too much—which is exactly what makes it reliable. You’ll use it for unpacking malware, editing memory, or even crafting exploits.
14. Interactive Behavior Analysis
This isn’t a single tool but a methodology—one that tools like Anyrun and Cuckoo support. Interactive behavior analysis lets you engage with malware during execution, allowing you to trigger hidden functionalities.
For example, some malware activates only after clicking something or entering input. By interacting manually, you gain insights automated systems might miss. It adds a layer of depth to dynamic analysis.
