Experts have discovered bugs in the 5G protocol that allow tracking location and arranging of DoS attacks

AdaptiveMobile specialists have published a report on new bugs in the 5G protocol, thanks to which it is possible to disable network segments (DoS) and steal user data, including location information. he issues identified are related to the 5G network partitioning mechanism that allows operators to split their infrastructure into smaller blocks dedicated to specific purposes (for example, automotive, healthcare, critical infrastructure and entertainment, and so on). The discovered vulnerabilities can be exploited in hybrid mobile networks, where 5G is mixed with older technologies. Such options will be found in the real world in the next years, when 5G technology will gradually replace the rest. Attacks are possible due to the lack of mapping between application and transport layer identifiers, …

Vulnerabilities in old GTP protocol could affect 4G and 5G networks

Experts cautioned that vulnerabilities in the old GTP (GPRS Tunneling Protocol) could quite seriously affect the operation of 4G and 5G networks. n reports published last week and in December 2019, Positive Technologies and A10 Networks described in detail a number of vulnerabilities in this protocol. In particular, are known the following problems: Disclosure of subscriber information (including location data that can be used to track users); spoofing, which can be used by scammers, as well as for attacks that allow posing as another user; denial of service (DoS) attacks on network equipment, resulting in massive disruption to mobile communications. Researchers explain that mobile providers will be forced to support GTP in their 5G networks, and because of this, users …
