“Security authorities in multiple places have issued safety tips: Be wary of Bluetooth ‘invisible traps’.”

Recently, public security and national security departments in many places have issued safety tips warning that keeping the Bluetooth function on your phone for a long time poses hidden risks. Criminals exploit vulnerabilities in Bluetooth technology to induce people to connect with unknown devices through silent pairing and phishing methods, resulting in intercepted calls, tracked locations, and stolen personal information. Wang Yuanyuan, an expert from the China Computer Federation, pointed out that attackers can activate microphone monitoring without user consent or use Bluetooth signals to determine targets and track their locations, and even implant malware to steal sensitive data such as account passwords. Prevention suggestions include updating system versions promptly and avoiding pairing with unknown devices in public places; if you accidentally receive unknown files, be sure to use security software to remove viruses.
