A research team has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street.

A research team led by Rice University's Edward Knightly has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street.

Wireless backhaul links, crucial for the backbone of modern communication networks connecting end users to the main networks, have been assumed immune from eavesdropping because of their underlying physical and technological barriers. As wireless technology advances into the realms of 5G and beyond, ensuring the security of these networks is paramount. The Rice team's work is a significant step toward understanding sophisticated threats such as MetaFly and also safeguarding the communication infrastructure.
