Daniel Gruss didn’t sleep much the night he hacked his own computer and exposed a flaw in most of the chips made in the past two decades by hardware giant Intel Corp .

The 31-year-old information security researcher and post-doctoral fellow at Austria’s Graz Technical University had just breached the inner sanctum of his computer’s central processing unit (CPU) and stolen secrets from it.
