Just converted a month ago from windows 10 to kbuntu 24lts The first thing is really weird bugs when dealing with multi-monitors in plasma/sddm (getting into UI locked states or xrandr settings not sticking for whatever reason). The second annoyance is not having first party support for peripherals like my mouse and webcam (looking at you Logitech) or generally thick client software that has windows/macos candidates but not Linux. Third is publishers with anticheat DRM being extremely hostile to VFIO gaming. EA announced Apex losing Linux support and recently they just blocked all their EAAC protected games from running on VM.
And even despite all that and more I am so happy to be rid of windows as a daily driver.
And what will homeland security or the FBI get out of it after concluding that that these "dudes" are two well known talented security researchers trying to conduct responsible disclosure to make air travel safer?
It arguably would have been smarter for FZ to show a video using an SDR dongle/android phone than hobbyist antenna construction if they were trying to drive home the point of simplicity.
Advocating on behalf of the devil: ease of access for determined attackers is not the concern. It's more the undetermined attackers they are worrying about enabling. (again I do not agree with law as the solution to this)
Absolutely agree the ban is ridiculous, but lets not now humbly hide the fact that FZ makes this way easier than the workflow shown in the video. Even ignoring the antenna construction you still need to record the data and post process it using a laptop and 3rd party software.
I too disagree with the Canada ban, however I think the regulators are more concerned with how easy this can be done with a flipper zero. The moment you took out a soldering iron to build an antenna filter you've increased the complexity to the point where the regulators are no longer concerned. Yes this is still very dumb imho.
If physical (evil maid attacks) are not in scope I fail to see the concern. To turn the FPGA into a malicious device you would have to gain root access to the system hosting it. So by the time the attacker is able to gain the ability to program the device, there is little need to even make it malicious. One could argue that it adds persistence vector to malware, except that the device likely will get reprogrammed over and over during normal operation. If malware authors wanted persistence they would likely target firmwares of random flash roms on chipsets and commodity PCIe cards that are less likely to be re-programmed. Lastly, the only other valid concern possibly more dangerous than root access is perhaps a remote attacker programming a bitstream to completely fry the FPGA faster than the power regulators can react and thus killing an expensive chip. That one is concerning.
Sure, but aren't you connecting your general purpose serdes to a peer PCIe controller? I don't understand why having raw serdes control is a security concern in this regard unless you are trying to find exploits at the physical layer...
In any regard, a lot of threat models (including mine) consider installing hardware (especially an FPGA) as a trusted action.
It's because generally I do like their product at a $6/mo price point. It's leagues better than FM radio. I just don't like their billing/promo practices and so these are the tricks to protect yourself as a consumer.
This is exactly why I place SiriusXM on a virtual credit card and a throw away email. I sign up for $6 per month SiriusXM promo with a $7 per month ceiling on the virtual card. When the 7th or 8th month comes around and the offer expires they have the audacity to charge $22+ for this content. The overcharge is caught and they don't get my money, and I'm happy to receive the disconnect signal.
Is it a common practice for commercial airliners to alternate between being used on a Hollywood set and for regular commercial air travel? Given how important failure analysis is in the airline industry, wouldn't this added complexity in the usage patterns of a commercial jet be a concern?
And even despite all that and more I am so happy to be rid of windows as a daily driver.
