Excellent article and something with extraordinary repercussions.
The world’s largest supplier of mothersboards, Supermicro, was caught adding spy chips to silicon they fabed for such companies as Amazon and Apple. All these parts had one thing in common: a Chinese contractor. One of the first cases was caught at Portland’s own Elemental technologies. A 3 year investigation showed almost 30 companies had their hardware infiltrated.
What does the chip do? Basically – it opens everything.
This system could let the attackers alter how the device functioned, line by line, however they wanted, leaving no one the wiser. To understand the power that would give them, take this hypothetical example: Somewhere in the Linux operating system, which runs in many servers, is code that authorizes a user by verifying a typed password against a stored encrypted one. An implanted chip can alter part of that code so the server won’t check for a password—and presto! A secure machine is open to any and all users. A chip can also steal encryption keys for secure communications, block security updates that would neutralize the attack, and open up new pathways to the internet. Should some anomaly be noticed, it would likely be cast as an unexplained oddity.
The strength of the Earth’s magnetic field is about 30 microtesla. The magnets in an MRI machine clock in at about 3 tesla, and the approximate magnetic field of a white dwarf star is about 100 tesla.
So just think about how powerful this 1,200-tesla magnet created by Shojiro Takeyama and his colleagues at the Institute for Solid State Physics at the University of Tokyo.
To achieve that intensity, Takeyama and his team pump megajoules of energy into a small, precisely engineered electromagnetic coil, the inner lining of which then collapses on itself at Mach 15 — that’s more than 3 miles per second (5 kilometers per second). As it collapses, the magnetic field inside gets squeezed into a tighter and tighter space, until its force peaks at a tesla reading unimaginable in conventional magnets. Fragments of a second later, the coil collapses entirely, destroying itself.
The last time Takeyama switched on his super-strong magnet, it blew out the heavy door of the lab that contained the machinery. Check it out here:
