A team of researchers from the University of Florida and CertiK discovered a smartphone hack that can burn the device while charging wirelessly. In this respect reports Anti-Malware portal.
The essence of the attack, called VoltSchemer, is that the attacker can create electromagnetic interference that affects the operation of the charger. This allows it to control and change the voltage supplied to the smartphone. Researchers conducted experiments on nine popular models of wireless chargers. They found that all chargers had hardware flaws that made them vulnerable to VoltSchemer.
An attacker can use VoltSchemer for two purposes: issuing voice commands or overheating the smartphone. In the first case, one can activate the voice assistant on the smartphone and make it perform various actions such as sending messages, making calls, making purchases and much more. In the latter case, it can heat the smartphone so much that it may malfunction or even explode.
To prove their claim, researchers heated the Samsung Galaxy S8 smartphone to 352.4 degrees Celsius; This significantly exceeds the safety limit of 280 degrees for Qi wireless charging.
