Evil Twin, KRACK, PMKID, rogue 802.1X, BLE. $40 of hardware extends the perimeter past the building.

Wireless networks extend the perimeter beyond the cable. The perimeter used to be “physically at the office.” Now it’s “anywhere our Wi-Fi reaches.” Attackers with $40 of hardware can operate from the parking lot, the coffee shop next door, or a drone hovering above. This module covers why wireless attacks remain operationally relevant in 2026 — and what actually hardens the environment.

Why this happens

Wi-Fi’s design trade-off: discoverability for usability. Client devices constantly broadcast “looking for my home network,” “looking for my office network,” etc. Rogue access points imitate these networks. Client connects. Attacker is in the traffic path.

Additionally: WPA2-PSK (shared key) networks allow any attacker on the same network to intercept each other’s traffic after the 4-way handshake is captured. Enterprise networks (WPA2/3-Enterprise with 802.1X) are better but have their own misconfigurations.
