MITM on PSTN -- novel methods for intercepting phone calls

In this talk the author proposes a novel method for intercepting phone calls over PSTN, including mobile networks.
We'll briefly each discuss the necessary components of the attack, including Caller ID spoofing, SS7, call diverts, and social engineering, and then join the all together to form the novel attack method.


This talk revisits the theme of personal privacy in the digital world, this time centring around the "I've got nothing to hide" argument. A beam of intensive light is shed on the motivation behind caring about one's privacy. We go in depth into what we can do to stay private and should we even try to do it at all. We talk about where we as an global society were able to fix privacy and where we have failed. New topics previously not covered are discussed, such as AI/LLMs.
