Researchers uncover 4G LTE exploits that can be used to spy, spoof and cause panic

Vulnerabilities in a common wireless telecommunications standard could allow hackers to send a fake emergency alert message to almost anyone’s smartphone. Researchers from Purdue University and the University of Iowa say they’ve discovered 10 new vulnerabilities in the 4G LTE protocol that can disrupt victims’ devices in several ways. They present the new findings in a paper published last month that showcases a tool they developed in order to detect such vulnerabilities. Among the new attacks, the researchers highlight an authentication relay attack, which they say allows an attacker to connect to an LTE network while spoofing another existing device’s identity and location. This is done without having legitimate credentials. “Through this attack the adversary can poison the location of the victim device in the core networks, thus allowing setting up a false alibi or planting fake evidence during a criminal investigation,” the paper says. The researchers explain that the 4G LTE protocol […]
