rozzin: The idea of `travel kit #raspi' does lend a certain appeal to the #Pi-Top #hardware, similarly to realization from #OLPC that kids really do need to be able to take their !education tools with them. Wondering why nobody seems to be talking about that.

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
