Flaws in 4G and 5G can lead to spying on location and calls, researchers find
A group of security researchers has revealed that newly discovered flaws in networks could let hackers eavesdrop on calls or track a phone owner’s location. Worse, the problems extend beyond just the widely used 4G, and into the next-generation 5G.
TechCrunch first reported on the researchers’ paper, which is set to be presented at a security symposium tomorrow.
In the paper, the researchers outline an attack called Torpedo, which can be used to determine whether a device is in a certain location. The attack exploits an issue in how devices send “paging” information when calls or texts are received. By making several calls continuously, a malicious attacker can take advantage of the paging…
