In this paper we are the first to present and discuss multiple detection capabilities from the network operator’s point of view, and evaluate them on a real-world cellular network in cooperation with an European mobile network operator with over four million subscribers. Multiple countermeasures have been proposed recently to detect such devices from the user’s point of view, but they are limited to the nearby vicinity of the user.
They are readily available as commercial products as well as do-it-yourself projects running open-source software, and are obtained and used by law enforcement agencies and criminals alike. We finally propose quick fixes and recommended remediesĪnd discuss security insights and lessons we have learnt.Īn IMSI Catcher, also known as Stingray or rogue cell, is a device that can be used to not only locate cellular phones, but also to intercept communication content like phone calls, SMS or data transmission unbeknown to the user. We validate these proof-of-conceptĪttacks in a controlled environment in one major US carrier which supports more Some are even prone to million-dollar loss. Services over 27 industries are vulnerable to at least one above threat, and They might result in distressing account hijacking,
These attacks are contact-less without physically accessing As a consequence, such weaknesses can be exploited to launchĪttacks against a targeted individual, a large scale of mobile users and even However, its shields to messaging integrity and userĪuthentication are not in place, while the legacy security mechanisms in 2G andģG are in vain. Particular, messaging service over " has to shift from the a conventionalĬircuit-switched (CS) design to the packet-switched (PS) paradigm as 4G LTE These mobile services are exposed to new threats raised by this change. Technology independently advances to the latest IP-based 4G LTE, we find that Such carrier-grade text service has been widely used toĪssist versatile mobile services, including social networking, banking,Į-commerce, mobile-health, to name a few. Phone number, it aims to provide mobile-friendly, always-online, and even more Through associating an online account with a personal One main option is to use mobile text service (i.e., In hand, many services choose to offer alternative, usually more convenient,Īpproaches to authenticating and delivering the content between mobile usersĪnd service providers.
