(based on Version 2004, Build 19041) is a specialized, third-party modification of Windows 10 designed specifically for penetration testing , Red Teaming , and cybersecurity professionals . Unlike standard retail versions of Windows, Ninjutsu OS is a "pre-packaged" environment that arrives pre-configured with over 800 security tools, system tweaks, and performance optimizations intended to turn a standard workstation into a powerful security laboratory. Core Architecture and Base Version
★★★★☆ (4/5) – Minus one star for security trade-offs.
If you want a more private or streamlined Windows experience, the safest path is to:
Ninjutsu OS was defined by its core features, which revolved around "removing" and "adding" to the standard Windows experience:
Windows 10 Pro version 2004 (May 2020 Update). Build Number: 19041.
: Compatibility with a wide range of software and hardware seems to be a strong point, as one would expect from a Windows 10 Pro version. Users have reported successful usage with various applications, from office software to development tools and games.
Comes pre-configured with privacy-focused utilities such as Proxycap , Shut10 , WPD10 , and Simple DNSCrypt to minimize telemetry and protect user identity.
One of the biggest challenges of running hacking tools on a standard Windows machine is that Microsoft Defender instantly quarantines security scripts and exploitation binaries. Ninjutsu manages these policies meticulously to keep your testing tools from being deleted, while still maintaining core system stability.
Including Burp Suite Community Edition. Reverse Engineering: Tools for malware analysis. Installation and Security Considerations
Microsoft’s original 2004 update introduced:
This was a controversial move. Ninjutsu OS was not a pirated copy of Windows; it required a valid license to function. The developer, Hasan, strongly rejected the accusations, stating the project did not contain any violation of Microsoft's rights. Nonetheless, GitHub, owned by Microsoft, quickly complied, and the project's repository was taken offline.
In the world of cybersecurity and IT customization, Linux distributions like Kali Linux have long been the go-to tools for penetration testing. However, a fascinating project emerged in 2020 that aimed to change that: , based on Windows 10 version 2004, build 19041. This wasn't just a standard Windows install disk; it was a heavily modified, "weaponized" operating system, packing hundreds of hacking and security tools into a familiar Windows environment.
Ninjutsu retains these core improvements while removing the “noise.” On build 19041, all security patches up to mid-2020 are integrated, making it stable for offline or gaming-focused rigs.
