<xentrac>btw there was a discussion of the Karger–Thompson attack on the orange website yesterday https://news.ycombinator.com/item?id=49575515

<xentrac>prompted by this paper about backdooring strip(1) https://arxiv.org/abs/2607.24888

<xentrac>and colinsane mentioned nixpkgs's 181-byte hex0-based seed in the discussion https://news.ycombinator.com/item?id=49603213

<xentrac>and fjfaase (Frans Faase) linked to his T-diagram of live-bootstrap: https://fransfaase.github.io/Emulator/tdiagram.html https://news.ycombinator.com/item?id=49603824

<roconnor>> I am trying to imagine how the magnet could be compromised. Could you theoretically embed an electromagnetic and a controller within a decoy magnet and somehow detect what was being recorded and subvert it? Probably not but... No, just probably not. — cure_42

<matrix_bridge><Andrius Štikonas> Electromagnet would need power

<matrix_bridge><Andrius Štikonas> Should be easy to detect

<roconnor>electomagnetic kinetic energy harvesting. :)

<roconnor>powered by the unsteady hand

<lanodan>magnet compromised by embedding a quartz cut at exactly the right angle

<xentrac>yes, I enjoyed that comment too

<lanodan>That said we do have some sort of electro-magnets with controllers: RFID/NFC/… tags

<xentrac>the other day (on Hackaday?) I saw a link to a guy who put an NFC-powered LED on his business card

<xentrac>so you touch it to your NFC-reading phone and it lights up, despite not having a battery of its own

<xentrac>I think he reported getting ≈10mW out of it

<xentrac>This was not the one I saw: https://hackaday.com/2017/10/25/nfc-enabled-business-card/

<xentrac>nor this one: https://hackaday.com/2026/08/31/building-an-energy-harvesting-business-card/
