David: If you are reading this, your site has very annoying "smooth scroll" that breaks scrolling for all mac users and also breaks the "back" shortcut on mac trackpads. Would recommend removing this: https://www.davidsopas.com/wp-content/themes/blg/framework/j...

The site works fine for this Mac user. (Safari 11.0.2, High Sierra)

On Sierra here:

* Chrome 63.0.3239.108 - broken

* Safari 11.0.2 (12604.4.7.1.4) - works fine

Not all mac users - it is working just fine for me. (Chrome 63.0.3239.84, High Sierra)

Fine on Firefox 57.0.1, High Sierra

What are thoughts on what one could potentially achieve with connectable devices?

Usable, but annoying, on a Thinkpad trackpoint.

So the idea would be to see how easy it is to hijack these devices wit driveby attacks?

I'd think passive data collection would be more interesting (for nefarious purposes), considering that BTLE is widely used for sensors and in particular for sensors that record very personal data like heart rate.

There is much better hardware out there. The Ubertooth devices can pick up BLE, and can also plug into basically any antenna you want. It's been a while since I played with it, but a few years ago my ubertooth was grabbing LAPs without difficulty. It's not a dirt-cheap device (150$ all in) but is open and available from a variety of sources.

What nefarious things can you do with knowledge of someone's heart rate though?

Spoofing HR and power telemetry for opposing running/cycling/triathlon teams. I'd send it slightly low, say 3-5bpm, so the target overexerts themselves.
