Many router manufacturers used static algorithms to generate default PINs based directly on the router's MAC/BSSID address (e.g., ComputePIN, Stefan大众, or Zhao algorithms). Dumpper 91.2 contains a database of these algorithms, allowing it to guess the correct PIN instantly without performing a slow brute-force attack. Step-by-Step Operational Workflow
