Security issue in Apple Airdrop allow attackers to steal personal information SHARE A security issue in Apple Inc.’s AirDrop feature can allow an attacker to steal personal information from an Apple user. Detailed April 21 by security researchers at the Technical University of Darmstadt in Germany, the security issue was first discovered two years ago but despite their contacting Apple in May 2019, the issue still exists. Using the vulnerability, attackers can learn the phone number and email address of an AirDrop user — even a complete stranger. To do so, all they require is a Wi-Fi capable device and to be in physical proximity to a target. They can initiate the discovery process by opening the sharing panel on an iOS or macOS device.
