It is striking that these vulnerabilities are not only in the current 4G networks, but also affect the new 5G standard that promises to improve both speed and security, and is that the researchers point out that these attacks can overcome the new protections that are I thought they could hinder intrusions on mobile phones.

Syed Rafiul Hussain, one of the authors of the research, commented: "Anyone with a little knowledge of cellular paging protocol could carry out one of these attacks."

Three dangerous attacks

All information will be revealed on Thursday at the Security Symposium on Networks and Distributed Systems in San Diego, but before that the document was shared with TechCrunch and it is mentioned that the attacks are called Torpedo, Piercer and IMSI-Cracking.

Torpedo takes advantage of a vulnerability in the paging protocol to know the user's location, Piercer allows the attacker to know the IMSI (International Mobile Subscriber Identity by its acronym in English), and IMSI-Cracking is used to force an IMSI number in 4G networks and 5G.
