Drones can pose a significant risk to wireless network security. How?

Through a method known as warflying.

Warflying is an advanced form of wardriving, where instead of scanning for insecure networks from a vehicle, a drone or radio-controlled airplane is used to gather information from a high altitude. This technique can identify access points that lack WEP encryption, with many still using default SSIDs, creating vulnerabilities for attackers, especially over critical infrastructures.

Warflying is also used for penetration testing, vulnerability assessments, and gathering details about network connections and operating systems.

To protect against warflying attacks, it is essential to use WEP encryption, change default SSIDs, set strong passwords, limit network access, and implement a network intrusion detection system.
