A group of academic researchers from the University of Florida and Web3 smart contract auditor CertiK have developed new attacks that lead to wireless charger takeover through power supply voltage manipulation.
The theoretical attacks, VoltSchemer (PDF), target vulnerabilities in wireless charging systems that could allow adversaries to damage charging devices, manipulate voice assistants, and circumvent Qi standard mechanisms to damage items exposed to intense magnetic fields. According to the academics’ research paper, the attacks exploit voltage noises from the power supply and do not require modifications to malicious chargers.
An attacker could use this new type of attack to modulate the magnetic field generated by the charger, resulting in unintended voice commands.
