BadPower attack corrupts fast charger firmware, overloads smartphones

Security researchers found a way to manipulate fast charger firmware to cause damage to connected devices. China-based research lab Xuanwu Lab detailed the technique, dubbed BadPower, in a recent report. Xuanwu is part of Chinese tech giant Tencent. BadPower works by corrupting the firmware of fast charger bricks. The firmware in these bricks communicates with connected devices like smartphones to determine the correct amount of power to deliver to the device. For example, a phone that can’t accept a fast charge would default to the standard 5V output, while phones with fast charging capabilities would receive 12V, 20V or higher. According to the researchers, BadPower alters the default charging parameters and delivers more voltage than the receiving device can handle. Increased vol...
