While they're okay on paper, they managed to burn a lot of customers in regards to the add-on wifi 7 module.
Quite a few of the modules went out without their eeprom programmed correctly, and all of them appear to be plagued by quite mediocre performance from (alleged) inadequate RF shielding on the card.
It looks like they've revised the design, but it's peeved off quite a few of the Banana Pi/Sinovoip customers who have bought them with the intention of using it as a router/ap with their R4. (It's dual-PCIe fingers with unique spacing and requires out of spec PCIe voltages, so it's only practically usable with a BPi R4.)
At the very least, the customers using them as wired-only routers are likely to be having a slightly better experience.
It did however deliver the hilarious quote "The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia", in regards to end-to-end encrypted messaging.[1]
It went down as well as about you would think it would.
I suspected something along these lines was possible when I looked at this provider a couple months ago.
If I recall, I had a fairly decent view of their various checks because it was delivered completely unminified, including a couple amusing sections and unimplemented features. (A gesture detector with the middle finger gesture in the enumerable commented out, for example...)
Another attack vector that I speculated upon was intercepting and replacing their tflite model with ones own, returning whatever results required.
Additionally, I believe they had a check for virtual camera names in place, as checks would quietly fail with a generic message in the interface, but show the reason as being virtual camera within responses. (Camera names are mutable though, so...)
If I recall, for something like GPON or XGS-PON, you end up having to clone the various attributes of the original for it to work properly. This typically includes serial number, hardware id, firmware identifiers, etc.
Qualcomm kind of does this with their XPAN extension, sends the audio over local network. I believe it's mostly a proprietary solution though, so I haven't seen any serious attempts to re-implement it yet.
> Most vendors gave the security researchers either silent treatment or were slow, even after Airoha published fixes. Jabra was one of the positive outlier, Sony unfortunately negatively.
While I don't recall Sony issuing an advisory, I believe the users of their app would have started getting update notifications since they (quietly) released firmware updates.
> This means there is great opportunity for Linux users to control their Bluetooth headsets, which for example is quite nice in an office setting to toggle "hearthrough" when toggling volume "mute" on your machine.
I think most vendors are using custom services with their own UUIDs for settings such as this.
Regardless, I believe there are open client implementations for some of the more popular devices. Gadgetbridge comes to mind in regards to Android, not sure about any Linux equivalent.
It did a great deal more than that. It also allowed the toggling of VoNR, which apparently affected the fallback behavior of some people's services. (Ie. It would fall back to LTE and not roam back to 5G data unless nudged manually)
However for me, it would enable backup calls over a secondary sim card's data, which would allow text and calls overseas without the usual extortionate charges. Oddly enough, I believe that toggle is enabled for my carrier... but only on iOS.
The major carriers perhaps, but support among the MVNOs isn't universal. Number sharing support for smart watch usage is almost non-existent among the MVNOs in Australia.
Eg. ALDI (yes, the German supermarket chain run a MVNO in Australia), have been saying esim support in the future since 2021.
For a second I thought this was referring to the other reset bug on Polaris, Vega and Navi. (These apparently have broken Function Level Reset sequences, requiring quite specific reset code as a separate module or a system reboot to bring back to a working state.)
