Security researchers have warned of flaws in medical implants in what they say could have fatal consequences. The flaws were found in the radio-based communications used to update implants, including pacemakers, and read data from them. From a BBC report:By exploiting the flaws, the researchers were able to adjust settings and even switch off gadgets. The attacks were also able to steal confidential data about patients and their health history. A software patch has been created to help thwart any real-world attacks. The flaws were found by an international team of security researchers based at the University of Leuven in Belgium and the University of Birmingham.
