Iirc the chips were supposedly found near the SPI flash for the BIOS if you can locate that, probably close to the IPMI/BMC chip.

- Scoundreller 8y agoSomeone needs to build nmap-style probe hardware that could be connected to the SPI bus and scan every device on it.
- mindslight 8y agoSPI works by paralleling all of the shared lines, and each chip having its own CS line. So you can't really enumerate like that, without already having enumerated the CS lines. I2C works closer to how you're thinking, but even there a hostile implant doesn't need to have an protocol-dictated address to corrupt someone else's traffic.
- jacquesm 8y agoOk, I will have a look if I can see anything interesting near the serial flash device.
