Security researchers at Purdue and U. of Iowa confirm what many security experts have long feared: there are serious security weaknesses in 5G that undermine the promised security and privacy protections. About a dozen vulnerabilities have been identified by the researchers, who report that the bugs can allow a bad guy to track your actual real-time location, send large numbers of people fake emergency alerts to trigger public panic or disconnect a 5G-connected phone from the network altogether. 5G was promised to be a more secure standard than 4G, able even to keep your data and voice safe from “stingrays” that present themselves as cell towers and spy on you. But, nope.
