Police around the world use this technology primarily to locate a phone (and therefore a person) with a high degree of accuracy, or determine who is at a specific location.

Although theres nothing stopping hackers and cybercriminals from using cell-site simulators to access peoples data, their cost and the need to be in physical proximity to the target device make them much less attractive than other types of attacks for any but the most focused and dedicated cybercrime operations.

Borgaonkar and fellow researcher Altaf Shaik, a senior research scientist at TU Berlin, found that major carriers in Norway and Germany are still putting out 5G in non-standalone mode, which means that those connections are still susceptible to stingrays.
