New Sni5Gect Attack Enables 5G to 4G Network Downgrade Without Fake Base Stations

Researchers from Singapore University of Technology and Design’s ASSET Research Group have developed a new cyberattack method called Sni5Gect that can downgrade 5G phones to 4G networks without requiring a rogue base station, marking a significant advancement in mobile network security threats. The attack, whose name stands for “Sniffing 5G Inject,” works by exploiting vulnerabilities during the communication setup between a 5G phone and the bas…
