چکیده
Voice over LTE (VoLTE) and NR (VoNR), are two similar technologies that have been widely deployed by operators to provide a better calling experience in 5G networks, respectively. The VoLTE/NR protocols rely on the security features of underlying LTE/5G network protect users' privacy such nobody can monitor calls learn details about call times, duration, direction. In this paper, we introduce new attack which enables adversaries analyse encrypted traffic recover any details. We achieve implementing novel mobile-relay adversary is able remain undetected using an improved physical layer parameter guessing procedure. This facilitates recovery configuration messages exchanged between victim devices mobile network. further propose identity mapping method our link victim's identifiers phone number efficiently, requiring single VoLTE protocol message. evaluate real-world performance attacks four modern commercial off-the-shelf phones representative, carriers. collect 60 hours networks execute 160 calls, use successfully identify patterns allocation traffic, Our experiments show works as expected all test cases, activity logs recovered describe actual communication with 100% accuracy. Finally, International Mobile Subscriber Identities (IMSI), Concealed Identifiers (SUCI) and/or Globally Unique Temporary (GUTI) numbers while remaining victim.
