For me, rowhammer has always been the most badass exploit I've ever heard of. I mean, flipping bits in memory by forcing an electrical current down a pathway over and over again? That's completely mind boggling. If I was hacked using rowhammer, I'd be so impressed I'd give the hacker whatever data they want and maybe even throw in a credit card

It's likely an inability to model worst-case current needs or clocking accurately enough to match reality when a large number of cells reinforce a draining property.
