      We had two of these boards ordered not 20 minutes before your Tweet, and thought perhaps it was you. That would be aside from the fact that, who would go to Twitter to ask or talk about important things like this?? Oh wait… never mind. Here's a close-up of one of the boards. pic.twitter.com/QlOpdfOleK

      Please don’t go all BadBIOS on us… there are pins in interesting places all over motherboards of many different manufacturers. You can build a complete conspiracy theory on the implications of a JTAG port.

      Yeah, fun challenge: identify all the regions on a board that a trillion dollar secret spy program would not be able compromise if they modified it. Are there any? Just claiming "it was in that area" proves nothing, it's *really* hard to pick an area where it's not possible.

      I dunno. Are there that many regions that you could reliably compromise the entire board’s operation with a tiny, inexpensive device that covers only, say, two wires?

      Given the number of sources on this story, we’re down to three possibilities: 1. Bloomberg perpetrates massive journalistic fraud, 2. US IC perpetrates massive fraud/conspiracy, 3. It’s true. I think answering hardware questions help to evaluate whether it’s (1).

      Or, 4), there is a desperate need for news to discredit China?

      There are a whole bunch of plausible explanations that don't require fraud. There was no fraud involved in #badbios or it's journalistic coverage, and dozens of experts (correctly) confirmed to reporters it was technically plausible.

          The stories even followed a similar vein, "experts have been warning for years this could happen", etc, etc. "professor foobar confirmed that a bios implant could do this", "senior research blah built a pc speaker network to prove the theory", etc, etc.

          BadBIOS was a single security researcher posting some dumps, which got repeated by clickbait lazy media with no confirmation. My point is: This Story Is Not That.

          The story lacks important details, such as the scale of the attack. If the scale was small, this might be even less effective than an interdiction hardware hack, and riskier attribution-wise than Stuxnet attack.

          So the story could be accurate as far as it goes, but overblown.
