The refers to the analytical scoring output generated by Zardaxt.py, an open-source, passive TCP/IP fingerprinting tool used to estimate a client's true operating system. By inspecting specific header fields within the very first SYN packet of the TCP three-way handshake , Zardaxt assigns structural probability weights to different operating systems. This scoring matrix is natively integrated into privacy-testing tools, network security suites, and commercial IP inspection platforms—most notably showcased via the BrowserLeaks TCP/IP Fingerprinting Test .

However, altering browser configurations does not automatically change the behavior of the underlying operating system kernel.

Zardaxt operates by inspecting the , specifically focusing on the initial SYN packet . Every operating system (e.g., Windows, Linux, macOS) implements the TCP/IP stack slightly differently. These variations appear in header fields and options, such as:

: The specific order and presence of options like Selective Acknowledgment (SACK) or Window Scaling. Zardaxt operates by inspecting the , specifically focusing

Most VPN protocols operate at the network layer, so the SYN packet still originates from the VPN server’s TCP stack. Therefore, a VPN connection does normally cause an os_mismatch . However, when combined with other signals (e.g., TLS fingerprints), Zardaxt can still contribute to a multi‑faceted detection system.
