bobjonkman2: bobjonkman2 favorited something by meitar: Fabrication-Time Attacks on CPUs: Ken Thompson was right While the move to smaller transistors has been a boon for performance it has dramatically increased the cost to fabricate chips using those smaller transistors. This forces the vast majority of chip design companies to trust a third party—often overseas—to fabricate their design. To guard against shipping chips with errors (intentional or otherwise) chip design companies rely on post-fabrication testing. Unfortunately, this type of testing leaves the door open to malicious modifications since attackers can craft attack triggers requiring a sequence of unlikely events, which will never be encountered by even the most diligent tester. In this paper, we show how a fabrication-time attacker can leverage analog circuits to create a hardware attack that is small (i.e., requires as little as one gate) and stealthy (i.e., requires an unlikely trigger sequence before effecting a chip’s functionality). In the open spaces of an already placed and routed design, we construct a circuit that uses capacitors to siphon charge from nearby wires as they transition between digital values. When the capacitors fully charge, they deploy an attack that forces a victim flip-flop to a desired value. We weaponize this attack into a remotely-controllable privilege escalation by attaching the capacitor to a wire controllable and by selecting a victim flip-flop that holds the privilege bit for our processor. We implement this attack in an OR1200 processor and fabricate a chip. Experimental results show that our attacks work, show that our attacks elude activation by a diverse set of benchmarks, and suggest that our attacks evade known defenses. The only practical defense against something like this for a layperson is to rely on technology that doesn't yet exist: open source hardware combined with next-gen home 3d printing capabilities. I'd be surprised if this sort of attack isn't already part of the NSA's black budget. #surveillance #hardware #NSA #security #infosec

The more dangerous backdoors are the ones the #NSA have access to, where the actual firmware of the disk is tampered with (giving possibilities to circumvent many security measures). And such tampering is already available publically for SD cards (and SSDs in general I guess) since bunnie et al. presented it on 30c3.
