Headphone flaw lets eavesdrop from 30m
A new technique called InjectEave guides researchers in Hong Kong to uncover serious security vulnerabilities in electronic devices, particularly headphones and smartphones. It can retrieve sounds and activities from distances of up to 30 meters through walls using directed wireless signals. The attack involves injecting a low-frequency signal into the analog components inside the devices, allowing sensitive information to be extracted despite digital protections. The results confirm that several devices from companies like Sony, HP, and Apple are vulnerable to this threat, with the capability to carry out attacks outside of laboratory settings and in real-world environments.
