Let's ban bridges because people can jump off of them!

Let's ban food because you can eat too much and become obese!

[–] Crow@lemmy.world 8 points 8 months ago

this would be more like banning shoes because people use them to go to bridges and kill themselves.

Security tools like Flipper Zero are essentially programmable radios, known as Software Defined Radios (SDRs), a technology which has existed for years, and in some cases can be built using open-source or simple over-the-shelf-components.

SDR is really cool:

That’s my local university; I listen to it all the time. It’s awesome to just listen to things from god knows where, knowing that it bounced around basically half the globe to reach me.

The tech itself is also really cool. You can have hundreds of people all listening and tuning to their own frequencies, all at the same time.

It's really cool.

SDR? I thought it just had a CC1101 for sub-GHz digital and an NFC/RFID module? CC1101 is very flexible but it doesn't do direct IQ sampling.

Open the firmware. Heck, open the hardware. Let companies come up with other authentication alternatives. Let the user or at least the mechanic decide what is used. It shouldn't be locked down to a vendor, or shoehorned into vendor lock-in situations.

Proprietary ≠ safe & secure

Security through obscurity is not security

[–] n3m37h@lemmy.world 4 points 8 months ago

Whaddya ya talkin bout? Locks have been so secure for the past 100 years!

I mean... An esp32 marauder is darn similar, and can be built.

We live in the information era, banning a novelty device with well documented methodology and diy alternatives is kind of low impact.

Edit: wait, you mean the car device firmwares don't you... I'd be a fan of that too, open sourcing and running vehicle software like a true FOSS community effort would lead to incredibly robust and full features. Would be absolutely amazing to watch.

It sucks that it's against a companies best interest to make a car that you can repair and maintain by yourself indefinitely. I can get electric motors, more energy efficient and potentially more environmental. But stuffing a car full of electronics that mimic what used to be mechanical dials and knobs is just building in an early death to the vehicle that doesn't need to be there. Not to mention the fact that vehicles are now being built with the ability to be unlocked with something like the flipper which is an active downgrade.

It's the 50:50 of requiring every technology that COULD be hacked by it to be remade, or just banning anything with a similar purpose outright

Last I heard the thing could hack into life-sustaining medical equipment
