New Attack Lets Hackers Decrypt VoLTE Encryption to Spy on Phone Calls

A team of academic researchers—who previously made the headlines earlier this year for uncovering severe security issues in the 4G LTE and 5G networks—today presented a new attack called ‘ReVoLTE,’ that could let remote attackers break the encryption used by VoLTE voice calls and spy on targeted phone calls.

The attack doesn’t exploit any flaw in the Voice over LTE (VoLTE) protocol; instead,
