750,000 Heart Defibrillators Prone to Hijack

Medical device maker Medtronic has warned that its heart defibrillators are prone to manipulation, which may result in life threatening situation for users. The flaw resides in the devices' wireless radio frequency (RF) component that fails to implement encryption and authentication. An attacker within the devices' proximity can therefore intercept the RF communication and manipulate the defibrillators implants. About 750,000 heart defibrillators are affected and Medtronic is developing software updates to address the vulnerabilities.
