  • An SDR can be made to jam, even if that is not the normal purpose. Just like a kitchen knife can be used to murder people, instead of its normal culinary purpose.

    Of course an F0 can’t clone a rolling code as-is. I never said it could. But it can harvest and replay a single or multiple consecutive codes just fine, providing the original key is not used in the meantime. Only need physical access to the key while it is out of range of the vehicle.

    This alone puts the F0 on dangerous ground as an “electronic device (such as a signal jammer) for use in theft of a vehicle or theft of anything in a vehicle”

    People have locked out their original keys by messing with this before.

    The point is that our laws are reactionary, vague, and open to too much interpretation.

    If someone gets shit stolen out their car and I happen to be nearby, then I will become suspect merely through possession. Even without intent.


  • Typical BBC reporting of anything technical.

    Keyless repeaters and signal amplifiers scramble the signal from remote key fobs inside people’s homes, enabling criminals to unlock cars.

    No, they don’t. The situation described is a relay attack on keyless entry/start. Jamming is used in a two stage attack, where the device intercepts the first signal and stores it without allowing the car to ‘see’ it by jamming. The user then tries a second time.

    This time the signal is intercepted the same way, and the first signal is played back to the car from the device. The second signal is stored and can be replayed later to bypass a rolling code setup.

    It’s very niche and the stored signal quickly becomes obsolete anyway.

    Sophisticated electronic devices used by criminals to steal cars are set to be banned

    Making or selling a signal jammer could lead to up to five years

    Jenny Simms said the possession, manufacture, sale and supply of signal jammers had provided an “easily accessible tool for criminals… for far too long”.

    These devices have no legitimate purpose

    Basically, fuck you if you happen to have or build a Software Defined Radio (SDR). Again with the UK ‘clamping down’ on something that does have plenty of legitimate use.

    I use an F0 for toying with my own equipment, as an interface for my smart devices and as a general purpose keyfob. I may be arrested just for possessing it.

    The crims will not care a jot and this only serves to restrict/annoy legitimate users.

    The fault and solution lies with the manufacturers who implement insecure tech, and with the users who blindly sacrifice pounds of security for ounces of convenience.



  • The USP here seems to be the traffic mangling used to disguise the connection. The client is open source, which is always good, but that means it’s probably easier for a bad actor to analyse and break that USP.

    Very limited payment options and macOS only currently. Feels like they’ve made a pretty webpage & rushed launch, instead of polishing the product/product availability first.

    Unfortunate that the term ‘Obscura’ is dominated by the band in search results.

    I will stick with stuffing an envelope with cash and posting it to mullvad, but this is definitely one to watch.








  • With good climate (not a rust belt) and being fortunate enough to not blow an engine, it should do well with diligent maintenance.

    Mostly why mine still goes. The bodywork is utter crap - full of scratches, dings, dents and the front end looks like someone dropped a running belt sander on it. Ex write-off. Mechanically though it is sound.

    My worry is the timing chain. Chains last longer than belts, but they are a dog to change and generally not worth the labour. It will be that or a crash that sends it to the great scrappy in the sky.

    Mid-90s a bit too early for me. I am fond of ABS (mandatory here since '04) and airbags ('98) at the very least. Not always a guarantee on cars of that era. Love the looks though.

    Best of luck with your teenager.
