Since you are asking I'm guessing they are not yours.

That means that BLE spam is still working for any BLE broadcaster that has the right "Manufacturer data"? will spam nearby iPhones?

Kinda neat, but why in the hell did they not put name of the chip into abstract, it's short.

Every time I see physical attacks on TEEs, I wish someone would put out a position paper on @hdevalence.bsky.social 's "guy with a glock" model

You're right but it itches me to finally start the Wireshark fork for Apple Continuity protocol I had sitting around with the nRF52840 DK and dongle sniffers. So let's find it.

When cheching file checksum/signature, readi is fast converting at 800-1000 MB.s, minimum of the reading 1 TB data | sha256 or signature check.

Adding Reed-Solomon checks that can on 500 MB blocks fix N errors is not hard but the app reads maybe more than it should

Apparently other USB SSDs (even physically larger with better thermal dissipation suffer from such slowdowns).

So I got ~1 kg copper heatsink from scrap, bought thermal-conducting adhesive pad just to try out how much it could cool down (because if 55°C is on outside, inside could be maybe 80°C).

Well the experiment worked, got down the temperature to 30-40 °C, the slowdown is also lesser, around ~330 MB/s.

Do you have some link summing up Canadian perspective? Ideally sum up and link to actual text, but first would be enough.

I know EU and US perspective (also how local laws give zero fuck about EU if they want), never heard Canadian yet.

Yeah, I knew instantly that the paper would be great with his amusing sense ripping into flesh.

Just now I realize I haven't heard from him for a long time, since some mailinglist and such went silent.
