They only make some bare PCBs. They can't glean any secrets from the pattern of squiggly copper traces, they can't embed anything nasty between the layers without anyone noticing, and they are not doing anything a thousand other PCB shops can't do if we were to need to change suppliers.
This is much ado about nothing. I'm not surprised RT joined in.
> Do fly by wire fighters have a backdoor into them via QRS-11 inertial flight guidance chips?
Of course not. The QRS-11 chip is a solid-state(ish) roll rate sensor. It's a gyro. It's not a radio receiver with a computer running mysterious unauditable code.
The idea that these things can be used to remotely cause planes to crash is something Able Danger started,.
>Maybe you could exploit a vulnerability or if some part of the circuit was particularly well attuned to receiving some form of RF
This might be plausible. It's a simple device. The marketing datasheet (PDF related) makes it sound like it uses analog outputs. And it's curiously sensitive to common mode noise at a particular frequency. However, such a analog system in a aeronautic application is undoubtedly very, very well shielded from outside interference. This is why I give the whole theory a big "nah".
>Exception PCB, a printed circuit board (PCB) manufacturer in Gloucestershire, south west England,
Oh.. This story is about something even being made in China.
>The inertial guidance chip needs information so that it knows where it is in 3D space. Feed it false data about course, height and speed and it could try to make fatal changes to the aircraft's course. The circuit that the inertial chip is fitted to controls engines and control surfaces.
Sure. But now you're talking about the rest of the system that integrates GPS data with inertial sensing. This poor innocent motion sensor, which does basically the same job as your inner ear, is being wrongly vilified.
>now it's everywhere and people cannot avoid it
…including the Monsanto executives and the scientists who do the testing. They and their kids all eat the same food that was sprayed with glyphosate that we do. And they don't seem terribly worried.
The people you read about having health problem as a result of glyphosate are people who are exposed to HUGE amounts of it, farmers who work with it all day and home gardeners who spray the stuff directly on vegetables and then eat them. It's these people who Monsanto is harming with unreasonably rosy promises of their products' safety.
