Di2 Security Vulnerabilities investigated by GPLama
Shane Miller aka GPLama is well known for his extensive turbo trainer tests and in-depth tech content. His YouTube channel contains a lot of great content for the more tech-minded riders among us.
Having recently bought a Di2 bike Shane has been looking into the little quirks and general Di2 weirdness – both the good and the bad. This time he investigates Di2 security and explains how someone else can use any Garmin head unit to change your synchro-shift settings any time they like.. and there’s nothing you can do about it. Other than disconnecting your EW-WU111/Wireless Unit of course.
While Shane makes it sound like riders will fall off their bikes and die, the real world implications of this issue are a bit less serious.
Nonetheless it is a big security issue and since this video was originally posted Shimano have made it possible to switch off BluetoothLE and ANT+ radio in the E-Tube application. Switching off the ANT+ signal should resolve this issue..
