> Lets hope none of these made their way into critical embedded systems eh.
Fake FTDI chips in critical embedded systems is the least of your problems, it's going to be a worry for many more common components that go into a critical systems. Fake power transistors, fake voltage regulators, fake op-amps, fake capacitors... you name it... it's a potential danger for all of them.
The difference here is that the component being faked here is complex enough for FTDI to have an option other than sending expensive lawyers round China on a stand-up comedy tour about fraud and protecting IP.
Whether it's a western company deliberately buying surprisingly cheap reels of components from cheaparsechinesechips.com rather than the official distributor in order to shave 10% off the BOM, or their Chinese PCB manufacturer doing the same behind the designer's back in order to increase their profit margin on a production run, I hope the effect of this is to shake up lax supply chain management in companies who have either deliberately or inadvertently let fake components find their way into their products.
