My DEF CON talk "Hacking jetskis - from Sea-Don't to Sea-Doo" got accepted 🥳

We'll be having some good fun - such as bypassing the immobilizer using a custom Flipper Zero app, building a custom diagnostic adapter, and some big plot-twists 🛥️

Opposite of solder-pr0n: Messed up the stencil solder application and was hoping for surface tension to fix it for me 🥲

The expired paste probably didn't help either

Told someone their "vulnerability report" is bs (result of an automatic scanner that has a false positive...)

This was the response 😑

Sometimes it’s nice to go back to basics:

Built firmware that’s just 246 bytes, uses no RAM at all, and runs parasitically from a 1-wire bus at just 0.2 mA.

Yet it emulates a full jetski key!

You can see voltage rising until the chip starts running based on the BOD threshold.

If you ever lose the keys to your older Sea-Doo Jetski you might find these bytes useful when talking to the ECU😇

Option A: Upgrade iPhone to iOS26 and have to use liquid glass

Option B: Get pwned by DarkSword malware

I don't know which one is worse
