Built on top of the VexTrio fingerprinting script documented in the original research below, extended with modern detection techniques from 2022–2025. Original Research All checks in the a-series (a1–a92) are derived from the VexTrio threat actor's fingerprinting script, originally documented by gi7w0rm: gi7w0rm — VexTrio's Browser Fingerprinting https://gi7w0rm.medium.com/vextrios-browser-fingerprinting-aeb721be6e30 VexTrio is a large-scale traffic distribution system (TDS) used to monetize stolen traffic by routing victims to scam, phishing, and malware pages. Their fingerprinting script ran silently on compromised sites to determine whether a visitor was a real human or a security researcher/bot before redirecting. --- How It Works Open Fingerprint.html in a browser. Click Run All Checks . Each check runs synchronously against the current browser environment and returns one of: Result Meaning -------- --------- aNN:0 / bNN:0 PASS — no anomaly detected aNN:1 / bNN:1 FAIL — browser flagged as suspicious/automated aNN:e / bNN:e ERROR — check threw an exception The verdict a0:1 means the browser was flagged as suspicious by at least one check. The Code Generator panel lets you export any subset of checks as a deployable JavaScript snippet in three styles (chained if-else, loop, standalone result map). --- Checks Reference ","default_branch":null,"files":null,"tree":[],"storefront":"/r/HackingLZ","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/HackingLZ/fingerprint_js/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
