According to news on February 24, a scientific team from the University of Florida recently demonstrated a VoltSchemer attack method that can melt mobile phones and cause fires during charging by invading wireless chargers.

针对无线充电板的新型攻击曝光:手机可加热至 81℃,金属夹加热至 280℃Note: This attack method is not easy to implement and requires physical access to the wireless charger. Therefore, ordinary consumers do not need to worry about this type of attack. Scientists are only demonstrating this possibility. VoltSchemer is an innovative attack method specifically targeting mainstream wireless chargers. By changing the output voltage of the device's power supply, it generates electromagnetic interference, which can affect smartphones to call voice commands or other gadgets. The Qi protocol itself regulates charging safety, and charging will usually stop after being fully charged. VoltSchemer exploits vulnerabilities in the protocol to render the protection mechanism ineffective. 针对无线充电板的新型攻击曝光:手机可加热至 81℃,金属夹加热至 280℃In a laboratory environment, the VoltSchemer attack can heat the Samsung Galaxy S8 phone to 81 degrees Celsius. In addition, the attack can also affect other metal objects on the surface of the charger. For example, placing a clip can heat it to 280 degrees Celsius. , can melt the flash drive, causing it to overheat and lose data. 针对无线充电板的新型攻击曝光:手机可加热至 81℃,金属夹加热至 280℃
