Probe Request Frame !link! 🆕 Top

Probe request frames are a significant vector for security analysis and potential attacks because they are sent in (unencrypted) prior to association.

To mitigate tracking, modern operating systems (iOS, Android, Windows) implement . Instead of using the globally unique hardware (burned-in) address, the device generates a random, locally administered MAC address for probe requests. probe request frame

In IEEE 802.11 (Wi-Fi) networks, the serves as a primary mechanism for active scanning. Sent by client devices (stations) to discover Access Points (APs), these frames facilitate network connectivity and roaming. While essential for network operation, probe requests also present significant privacy and security challenges, as they are typically sent unencrypted and contain identifying information about the transmitting device. Probe request frames are a significant vector for

| Frame | Direction | Purpose | |-------|-----------|---------| | | Client → AP (broadcast) | “Who is here?” | | Probe Response | AP → Client (unicast) | “Here I am, and here’s my info.” | | Beacon | AP → broadcast (periodic) | “I exist, here are my details.” | In IEEE 802
