Are you basing this off the photo in the Bloomberg article that shows a small (0402?) SMT package with three terminals?
I wonder if that's an actual photo of the chip in question.

This shows a 6-pin silicon chip inside a roughly 1mm x 2mm ceramic package – as often used for capacitors and other so-called ‘passive’ components, which are typically overlooked.
- dboreham 8y agoIt might be possible to mount an attack from a board location occupied by a legitimate passive component (or a single SOT-23 transistor, something like that). In that case the attacker would only need to replace a reel of legit passives in the PnP machine. Visually they'd be identical.
- nerfhammer 8y agoSOT-23 only has three pins, seems like it would be challenging only having one data pin. The alleged component in question had six pins, if it were passive it must have been a bank or array of passives since individual passives generally only have two pins each.
- jnbiche 8y agoBased on the captions in the original story, I think it's just a photo of a random signal conditioning coupler, which the chip in question was said to strongly resemble. But I'm not sure.
