Summary

Hide ▲

A team of academics from the Singapore University of Technology and Design (SUTD) has developed a new attack framework, Sni5Gect, that can downgrade 5G connections to 4G and crash phone modems. The attack leverages unencrypted messages exchanged during the initial connection process, bypassing the need for a rogue base station. The framework has been tested successfully against multiple smartphone models, demonstrating high accuracy in sniffing and injecting malicious payloads. The Global System for Mobile Communications Association (GSMA) has acknowledged the attack and assigned it the identifier CVD-2024-0096. The Sni5Gect toolkit enables passive sniffing and stateful injection, providing a new vector for 5G security research and exploitation.
