说明

这是2014年由media.ccc.de发布的一部演讲，主题归在Security & hacking。它讲的是telecom network security这一支里的具体问题，而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成：Tobias Engel's 31C3 talk shows how weaknesses in the SS7 telephone signaling network let companies and attackers locate, track and manipulate phones from anywhere in the world, with precision down to about 50 meters.这些读者给出的理由，核心是：HN cites it as the foundational demonstration that SS7 is insecure, relevant to arguments about SMS-based two-factor authentication.它贴着当时的技术，看的时候要记得那是那个年份的判断。从2017年到2021年，有1位不同的读者在1个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把telecom network security变成能跟着复述的例子。
