Counterfeit parts making their way into brand new U.S. military weapons

Pretty crazy how this is a problem. Scary too.

“Senate Armed Services Committee Chairman Carl Levin (D-Mich) just dropped a couple of very alarming tales during a hearing about counterfeit parts making their way into brand new U.S. military weapons.
Earlier this year, Boeing and the Navy found that the ice detection system on a brand new P-8 Poseidon was defective. The ice detection system is a critical piece of hardware designed to prevent tragedies by alerting pilots to the presence of ice on an aircraft’s control surfaces. Where did this defective part come from? China. A whole batch of a key piece of the ice detection hardware that was sent to the P-8 production line turned out to be used and worn out parts that were badly refurbished and sold to P-8 subcontractor BAE Systems as a new part, according to Levin.”

Side Channel Attacks

An interesting read on side channel attacks:

“The second story was about USB devices. Basically, they plugged a very precise voltmeter into an USB port and started recording the very small variations between 4.999V and 5V. With the same assembly-test-program-pattern-matching approach, they broke RSA again.” Link.
