As someone who works in the area of motherboards, chips, crypto, and bare epoxy boards, the Bloomberg article reeks from hell to high heaven. "Oh, these flashing ethernet lights show that it's being hacked." Uh, no. "This chip can be sandwiched between layers." Without a trace??? Yeah, some of those chips are small, but they can't just be "slipped in" at a whim.
And on and on.
Bloomberg stooped to supposition and speculation, and reported such as fact. Seriously, the worst presentations at Black Hat are better than the Bloomberg article. "Quod est demonstrata" does still have relevant meaning.
