Mobile computing means using portable devices like smartphones, tablets, or laptops to access information and applications without being limited to one place. It works with the help of wireless networks, internet, and software so that people can communicate, share data, and do their tasks from anywhere. For example, checking emails on a phone, using online banking apps, or finding directions with GPS are all part of mobile computing. As a student, I see it as a way that makes learning and daily activities easier because we can study, attend classes, or even submit assignments online while being mobile. In simple words, mobile computing gives us the freedom to stay connected and productive wherever we are.

Fascinating how Even though we did realized some of this with the mobile phone we still have a system that's so fragmented that it's fundamentally getting in the way of progress

Mobile Network Hacking, IP Edition. by Karsten Nohl, Luca Melette & Sina Yazdanmehr. Black Hat. London. December 2-5, 2019. 47 minute video. https://www.blackhat.com/eu-19/briefings/schedule/index.html#mobile-network-hacking-ip-edition-17617

Mobile networks have gone through a decade of security improvements ranging from better GSM encryption to stronger SIM card and SS7 configurations. These improvements were driven by research at this and other hacking conferences.

Meanwhile, the networks have also mushroomed in complexity by integrating an ever-growing number of IT technologies from SIP to WiFi, IPSec, and most notably web technologies.

This talk illustrates the security shortcomings when merging IT protocols into mobile networks. We bring back hacking gadgets long thought to be mitigated, including intercepting IMSI catchers, remote SMS intercept, and universal caller ID spoofing.

We explore which protection measures are missing from the mobile network and discuss how to best bring them over from the IT security domain into mobile networks.

Definition of "super-app"

Not yet common in the U.S., but exemplified by WeChat in China. This is a response to the decline in mobile app user tracking and the corresponding ad-tech. It is about capturing more time and attention from mobile computing uers.
