After developing those two more technical radio attacks, Plore dug into Armatix's patent diagrams. There, he found that when the watch's radio signal authorizes the gun to fire, an electromagnet moves a small metal plug to unlock its firing pin. So Plore ordered a $15 stack of magnets from Amazon. He found that by placing them next to the gun's body at a certain angle, he could immediately fire at will, with no watch in sight.

When the gun first fired without authentication, "I almost didn’t believe it had actually worked. I had to fire it again," Plore remembers. "And that’s how I found out for $15 of materials you can defeat the security of this $1,500 smart gun."

That Wired article references the DefCon 25 talk about hacking the Armatix smartgun.
^I attended that talk.

Here's the talk...

If you watch lock picking lawyer channel, it's not uncommon for really bad lock designs to be put in expensive products.

When you think about the space confines to work with in a firearm, designing a reliable, effective, mechanical locking system is challenging.

If firearms ever make the jump from mechanically activated primers to electrically activated primers (fire by wire) it would be much easier to incorporate a smart gun style user authentication interlock into the fire control electronics. You still have the challenge of making said electronics reliable in a form factor that will fit into space confines of a firearm that will hold up to duty use over the life expectations of the weapon.

The point of electronics integrations into mechanical contrivances acting as security systems is funny on the face of it. Think about what's going on: Someone puts a chip in a widget. The chip has a pin on one side that has a current on it and another pin on the other side where the current needs to go in order to turn the widget on. The job of the chip is to decide if the current gets from the first pin to the last pin. So, all one really has to do to defeat any electronic security contrivance is figure out how to make the chip immaterial. Either short the circuit or bypass the need for the electrical conductivity the chip is managing.
