  This research paper entails an examination of the Enhanced Wi-Fi protocol,
focusing on its control command reverse-engineering analysis and subsequent
demonstration of a hijacking attack. Our investigation discovered
vulnerabilities in the Enhanced Wi-Fi control commands, rendering them
susceptible to hijacking attacks. Notably, the study established that even
readily available and cost-effective commercial off-the-shelf Wi-Fi routers
could be leveraged as effective tools for executing such attacks. To illustrate
this vulnerability, a proof-of-concept remote hijacking attack was carried out
on a DJI Mini SE drone, whereby we intercepted the control commands to
manipulate the drone's flight trajectory. The findings of this research
emphasize the critical necessity of implementing robust security measures to
safeguard unmanned aerial vehicles against potential hijacking threats.
Considering that civilian drones are now used as war weapons, the study
underscores the urgent need for further exploration and advancement in the
domain of civilian drone security.
