ShowStopper
A Windows tool for malware researchers to explore and test anti-debug techniques across modern debuggers.
What is ShowStopper?
ShowStopper is a Windows-based tool designed to help malware researchers explore and test anti-debug techniques. It allows researchers to attach debuggers to its process and observe how debuggers behave when encountering various anti-debug methods, with function addresses printed for comparison. The tool compiles techniques from real-world malware and published sources, supporting modern Windows versions and debuggers.
Malware researchers, reverse engineers, and security professionals who need to analyze or verify anti-debugging techniques in Windows environments.
Researchers choose ShowStopper for its curated collection of real-world anti-debug techniques and its practical, debugger-agnostic approach to testing and comparing debugger behavior, making it a valuable resource for hands-on security analysis.
Overview
ShowStopper is a tool for helping malware researchers explore and test anti-debug techniques or verify debugger plugins or other solutions that clash with standard anti-debug methods.
Use Cases
Best For
- Testing debugger plugins against anti-debug methods
- Comparing implementations of anti-debug techniques across different debuggers
- Researching anti-debug behavior in real-world malware samples
- Verifying anti-debug solutions in Windows security tools
- Educational purposes for learning anti-debugging techniques
- Analyzing debugger vulnerabilities to anti-debug tricks
Not Ideal For
- Researchers analyzing 64-bit malware or using 64-bit debuggers exclusively
- Projects requiring cross-platform anti-debug testing on Linux or macOS
- Teams needing automated, scriptable anti-debug analysis without manual debugger attachment
Pros & Cons
Pros
Includes anti-debug methods sourced from real-world malware and published documents, providing a comprehensive library for research, as noted in the README.
Compatible with various modern debuggers like OllyDbg, x32dbg, and WinDbg, allowing flexible testing environments, per the system requirements.
Prints virtual addresses of anti-debug functions to the console, facilitating easy comparison and implementation verification, a key feature highlighted in the overview.
Supports Windows releases from 7 to 10, ensuring relevance for current operating systems, as stated in the system requirements.
Cons
Limited to 32-bit debuggers, which may not cover modern 64-bit malware analysis scenarios, a restriction mentioned in the system requirements.
No support for other operating systems, restricting its use to Windows-based research and limiting broader security analysis.
Requires researchers to manually attach debuggers and interpret console output, lacking automated analysis features, which can be time-consuming.
