A group of academics from South Korea have identified 36 new vulnerabilities in the Long-Term Evolution (LTE) standard used by thousands of mobile networks and hundreds of millions of users across the world.

The vulnerabilities allow attackers to disrupt mobile base stations, block incoming calls to a device, disconnect users from a mobile network, send spoofed SMS messages, and eavesdrop and manipulate user data traffic.

They were discovered by a four-person research team from the Korea Advanced Institute of Science and Technology Constitution (KAIST), and documented in a research paper they intend to present at the IEEE Symposium on Security and Privacy in late May 2019.
