Unlocking the Zardaxt OS Scoring Link: A Guide to Passive TCP/IP Fingerprinting zardaxt os scoring link
Zardaxt OS Scoring is a heuristic evaluation that estimates the probability of a remote device belonging to a specific operating system class. Unlike active scanners like Nmap that send probes to a target, Zardaxt is . It simply listens to the very first SYN packet TCP 3-way handshake
: It is frequently used in anti-detect and "humanizing" toolsets, such as untidetect-tools
"avg_score_os_class": "Android": 0.57, "Linux": 0.44, "Windows": 0.30 , "details": "os_highest_class": "Android", "highest_os_avg": 0.57, "perfect_score": 20.5 Use code with caution. Practical Applications for Cybersecurity and Privacy You need to run Zardaxt with root privileges
The "scoring" part of the tool compares these observed network traits against a database, assigning weighted scores to various OS classes like Android, Windows, macOS, iOS, and Linux. How the Scoring Algorithm Works
Zardaxt is an open‑source project hosted on GitHub. The main repository at NikolaiT/zardaxt continues to receive updates, including fingerprint database enhancements and compatibility fixes for newer Python versions. A more recent fork by starplanet/zardaxt also exists, adding live demo links and documentation improvements.
The scoring link transforms raw network data into actionable intelligence. Here are the two most common use cases documented by security professionals. Unlike active scanners like Nmap that send probes
These parameters often differ significantly between desktop and mobile stacks. IP ID & TCP MSS (1.5 pts each): These provide further granular differentiation.
Identifying if a user is trying to hide their true location or device type.
The "scoring link" refers to how well a captured packet matches the database. Exact Matches
