Sketcy option. $WORK was desperate for some STM32F42x parts and bought a few hundred from shady distributors (at ~20x the price)- the parts did arrive, their markings made sense, and they did even sort-of work (that is- the debug interface responded, the firmware could be loaded, but that was about it- they did not execute code). Also, the unique serial numbers of the chips were ... less than unique.
