An international mobile subscriber identity-catcher, or IMSI-catcher, is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users. [1]

2024年7月12日 · Classic IMSI catchers operate in a relatively straightforward way. Their primary goal is to collect a specific piece of data: the International Mobile Subscriber Identity (IMSI). This is a unique 15-digit number stored on every SIM card used to recognize individual subscribers of a mobile network.

2019年6月28日 · Section 3.1: Basic IMSI-catcher. Classic “IMSI-catchers” simply record nearby IMSIs, and then don’t interact with their target phones in a significant way beyond that. They quite literally “catch” (i.e. record) IMSIs by pretending to be real base stations and then release the target phones (Paget, 2010).

2019年8月19日 · By analysing incoming signalling traffic, and detecting and blocking these IMSI Profilers, mobile operators now have the opportunity to help protect their subscribers globally, regardless of how stealthy the IMSI Catcher is.

An IMSI catcher is an electronic device that tracks and intercepts mobile phone communications. IMSI catchers are also called Stingrays, rogue cell towers, fake cell towers, rogue base stations, cell site simulators, cell site emulators, or drop boxes.

2024年2月28日 · IMSI catchers, colloquially known as “Stingrays” after a popular brand, are sophisticated surveillance tools designed to intercept mobile phone communications. Their primary function is to mimic a legitimate mobile phone tower, tricking mobile phones within a specific area into connecting to them instead of the actual network.
