Saint SweynTooth, Son of Bluetooth
Patron of Bluetooth Low Energy devices, development kits everyone copies, and fitness bands.
Life
In February 2020 Matheus Garbelini, Sudipta Chattopadhyay and Chundong Wang of the Singapore University of Technology and Design published a family of flaws in the Bluetooth Low Energy software kits of seven chip vendors. A malformed packet sent by someone within radio range could freeze or reboot the device, and in some cases bypass its security; the victims included locks, sensors and medical devices. The name comes from Sweyn Forkbeard, son of King Harald Bluetooth.
Prayer
O Saint SweynTooth, who inherited his father's flaws, let our chips get updates even after they are sold. Amen.
How to celebrate
Celebrated by updating BLE device firmware, whenever the vendor remembers making them.
Like kit, like device.
