What is Red Check?
Red Check is a detection analysis platform designed for malware developers and security researchers who require accurate and actionable insights into file detection.
It performs deep Windows Defender signature analysis on your malware samples, identifying exactly why and where detections occur.
This allows you to precisely modify your files to evade detection efficiently.
By using Red Check, you eliminate guesswork, reduce development costs, and accelerate your time to undetectable binaries.
Powered by Windows Defender
Red Check uses a customized Windows Defender engine that is always updated to the latest version.
Your malware is analyzed directly against Defender's real, current signature database.
There are no simulations or estimations. Detection results are based on actual signature matching performed by a real Defender backend engine.
This guarantees accurate visibility into how your malware would be detected in live environments.
Reverse Engineering and Outflanking
Beyond signature detection, Red Check integrates a reverse engineering engine.
Whenever possible, Red Check will automatically reverse engineer and outflank detected payloads, exposing critical information about the original source code behind detections.
This gives you not only raw detection matches but also insights at the code level, allowing you to refine your binaries and neutralize detection signatures more intelligently.
Why Use Red Check?
Immediate Detection Cause Visibility
Identify exactly which parts of your file trigger detection: offsets, regions, section names, and code patterns.
Precise Outflanking and Decompilation
Reverse engineer and extract original code that caused the signature match whenever possible.
Save Development Time and Expenses
No more endless blind patching, rebuilding, and re-encrypting. Surgically adjust your malware based on precise forensic insights.
Accurate, Real-World Data
Detection results are based directly on the real Windows Defender engine and signature sets.
Secure and Private
- Files are automatically and permanently deleted from the server one minute after scan finalization.
- Neither the uploaded files nor the analysis results are ever submitted to antivirus companies, cloud reputation systems, threat intelligence databases, or telemetry networks.
- No cloud submissions. No sharing. Full operational security guaranteed.
