A GPS tracker used by elderly people and young kids has a security hole that could allow others to track and secretly record their wearers. It has an in-built SIM card that it used to pinpoint the location of the user, as well as provide hands-free communications through a speaker and mic. As such it is most commonly used by elderly people in case of a fall and on children whose parents want to be able to know where they are and contact them if necessary. But researchers at Fidus Information Security discovered, and revealed on Friday, that the system has a dangerous flaw: you can send a text message to the SIM and force it to reset. From there, a remote attacker can cause the device to reveal its location, in real time, as well as secretly turn on the microphone.
