Secret chips in replacement parts can completely hijack your phone's security

Booby-trapped touchscreens can log passwords, install malicious apps, and more.

People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device.

The Mafioso of old never allowed repairmen into their homes.  Stories abound regarding multiplicities of dead washing machines, TV's, etc.

It appears that their fears were justified.

On the other hand, these stories play right into the hands of those trying to kill "the right to repair" supported by the EFF.
