Pixie Dust Wi-Fi Attack — WPS PIN Extraction & Unauthorized Wireless Access CyberDudeBivash Threat Analysis Report
Executive summary What: The Pixie Dust family of attacks abuses weak or poorly implemented Wi-Fi Protected Setup (WPS) to recover the router’s WPS PIN (or related credential material) without needing to perform an online PIN brute-force over the air. This can allow an attacker to join a wireless network and obtain network access, bypassing pre-shared keys (PSKs). Why it matters: Many SOHO/SMB routers and some enterprise devices still support WPS or have vendor implementations with weaknesses. Successful exploitation can lead to lateral movement, credential harvesting on the network, device compromise, data exfiltration, and pivot to internal services. Who’s at risk: Home users, small offices, retail, branch offices, IoT-heavy environments, and any network where WPS is enabled or vendor defaults are in use. Action now: Disable WPS on all managed access points and home/branch routers. Enforce WPA2/WPA3 with strong PSKs or enterprise EAP. Monitor for new/rogue clie...
