VoltSchemer attacks work by exploiting voltage noises from the power supply and using electromagnetic interference to manipulate wireless chargers without the need for any malicious modifications to the chargers themselves. The researchers were able to show how such attacks were successful on nine top selling wireless chargers. The attacks can also alter chargers to overheat and ‘fry’ phones.

Since these attacks rely on setting up a malicious power source in a specific location, the advice is to use your own personal charging port, for example your one at home, or your own portable charger or plug where possible.
