EFF: The 5G Protocol May Still Be Vulnerable to IMSI Catchers
The 5G Protocol May Still Be Vulnerable to IMSI Catchers It’s hard to talk about the vulnerabilities in cellular technology without increasing the amount of fear, uncertainty, and doubt. There is already much uncertainty around cell-site simulators (CSS, aka Stingrays) , their capabilities, and how widely they are used. Partly this is because of the veil of secrecy that has surrounded the workings of commercial cell-site simulators thanks to the widespread use of non-disclosure agreements by the manufacturing companies like Rayzone and Harris Corporation. The privacy threats posed by CSSs are undoubtedly dire, but we need to keep our hypothesis about their capabilities and the scope of their use grounded in facts and research. One good source for research about potential capabilities for cell site simulators has been academia. A number of fantastic papers explore vulnerabilities in 2G , 3G , and 4G which are potentially the same ones exploited by commercial CSSs. The upcom...
