The popularity of cheap and DIY drones has made them a target for attackers using radiofrequency (RF) signals. Frequency hopping is a technique that can be used to mitigate the risks associated with RF warfare. However, implementing frequency hopping in cheap and DIY drones presents several technical challenges, such as the need for a stable clock and synchronization between the transmitter and receiver without rising hardware costs. Despite these challenges, frequency hopping can significantly enhance the security of consumer and DIY drones making much more challenging or even useless  anti-drone systems' role.

DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyers, federal government employees, security researchers, students, and hackers with a general interest in software, computer architecture, hardware modification, conference badges, and anything else that can be "hacked". The event consists of several tracks of speakers about computer- and hacking-related subjects, as well as cyber-security challenges and competitions (known as hacking wargames). Contests held during the event are extremely varied, and can range from creating the longest Wi-Fi connection to finding the most effective way to cool a beer in the Nevada heat.
