Why that over the debug probe firmware?

It doesn't have to be for that, but yeah, that's the target. At the time, a lot of keyboard designs were based around the pro-micro formfactor, so this made it more-or-less a drop in replacement.

I do this but better:

- caps + key = control + key

- tap caps = escape

- caps + space + key = ctrl, opt, cmd + key

All done in my keyboard firmware.

It's probably to keep the payload in SRAM for longer.

If it's the attack I believe it to be, basically it:

1. Acts as a debugger (core blocks touching flash) and writes a 2-part payload to SRAM.

2. Detaches the debugger, straps the boot pins to boot from SRAM (payload 1)

3. Resets the board via reset pin (keeping SRAM)

4. SRAM payload 1 runs (core blocks touching flash), configuring the FPB to 'overlay' the reset vector on flash with a pointer to payload 2

5. Flicks off the power just long enough for the hardware to reset, but not long enough for the SRAM to clear (this is where I think being cold helps).

6. Device boots 'unlocked' into 'flash', but the FPB hijacked the vector table and so the CPU immediately jumps to payload 2.

7. Payload 2 can now do whatever with flash (e.g. dump it out over UART or SPI)

Weird. I happen to be watching Malcolm in the Middle and I find a link to Malcolm in the Middle

Ah! I thought your wording was a hint (it's the viewer that thinks it's only 92 pages).

Oh yeah. I have the paperback 'bible'. I don't think that that one is a polyglot, though.

I feel like this tweet suggests that the PDF is a polyglot or an embedded second PDF.

I literally came to post the exact same line as my indicator that this was AI-generated. I ctrl-f'd first and sure enough I'm not alone in using 'key insight' as the canary.

I try to 'punish' for these and tip less than I would normally.

Are you using an agent? It can quickly notice the issue and fix it. Obviously if it's trained on an older version it won't know the new APIs.

You must have not tried this with an LLM agent in the past few months.

What did the function that called into it do with the result? If it was a simple "if rv != 0xabcd goto fail" the patch could probably be simplified to just... nop a few bytes.

In a very strange coincidence, I happened to read that first story in a book[1] I'm reading, just last night! What are the chances?

I don't get it?

    707000 = 1.46x
    x = 707000/1.46
    x = 484247

707000-464272 is more than 200k
