[@klausstock8020]

Polonium-210 might just work. The unassembled pieces will become quite hot already, so heavy cooling would mandatory all the time. When the time comes, cut off the colling, assemble the pieces and there you go. You don't need the gun-type assembly methods or the implosion assembly method (as used in conventional nuclear warheads), some spring-loaded mechanism which pushes your Polonium-210 pieces together should do. The already frigging-hot Polonium (a lone particle of 1g will already heat up to about 500°C (932°F)) will get even hotter when lumped together, melt when it reaches 254°C (489°F) and then boil at 962°C (1764°C). It might a very, very good idea to have it (together with the drive) in a very sealed high-pressure compartment. The "nice" part about such a Polonium-210 would be that it just generates heat (140W per gram of Polonium-210, so 100g of of this stuff could generate 14kW in a very small volume; note that 100g is the worldwide yearly production of Po-210), but no nuclear explosion. Bonus fun: while Po-210 is r not a chemical toxicant, it is a radiological one. In fact, less than 1µg (no, not milligrams, like the deadliest chemical poisons) is sufficient to kill a human. I'd expect a TLA agent to be somehow...reluctant to open an enclosure with a hard drive and enough Po-210 to kill 100 million people. There is one estimate that the LD50 of Po-210 is 50ng (yes, nano-gram) when digested and 10ng when inhaled (remember, the Po-210 inside your sealed pressure compartment is now boiling metal), so according to that estimate, 100g could poison 2 billion people, of which 1 billion would die. Another estimate for the LD50 is around 90ng, which would reduce the number of affected persons by a few 100 millions. Note that while Po-210 is highly radioactive and very deadly when inside your body, the radiation is quite harmless when the stuff is outside your body. A sheet of paper is sufficient to shield you from alpha radiation, as is the layer of dead skin cells on your skin. However, your skin only protects against the radiation, the Polonium itself will happily diffuse through your skin (or, for example, latex gloves) Verdict: yes, it could possibly work, but would be insane.

Yeah... focus on nuking the machine's RAM and CPU registers, plus the NVRAM of the controller, instead of the entire hard drive. If the keys are not kept anywhere else, and are sufficiently random that you have no hope of memorising them (or you never see them in the first place), rubber hose decryption is useless and the data on the platters will be indistinguishable from white noise. Assuming the key isn't kept on an unencrypted part of the drive as well, of course...

The key to thermite is that its not an explosion really just a hot metal, you have to make the metal fall onto the platter. your internal solution should work in a 2u data server with vertical disks. also, you have to take the drive top off for best results

[@snowdaysrule]

I know that a cd will "self destruct" if spun at a sufficiently high RPM. I wonder how difficult it would be to do the same to the platters in the hard drive? I doubt the spindle motor built into the drive would be powerfull enough to accomplish this, but it would be pretty cool if it could! Then the drives could just be programmed to destroy themselves

Unless you actually grind the pieces to dust, it's not very safe still. Bending, chopping and locally scratching/puncturing make it more annoying to recover data but not physically impossible.

+Cory Goodman Act of TERRORISM. Blowing up your computer, particularly in a public place, woud probably be just as bad, in the end, as whatever they might find on it. The best solution is fast encryption, followed by fast data corruption then progressive data wipe, with the power toggle disabled so they cant turn it off. Hopefully, before they figured out what was happening and how to shut it down, enough of your data would be destroyed. Really though, security is a compromise to convenience. The better your security, the more difficult your own access. If you keep everything but the file youre working on encrypted, youre reasonably safe, but that makes doing anything a task. Of course, thats really no more time consuming or complicated, than daily use of computer was 20 years ago. All about convenience.

Considering a "threat towards officer" usually lands you in jail for about 5 years, and "piracy" usually lands you in jail for 10-15 years, and piracy is what most would go for nowadays because it is so common and holds such high penalty, I say booby trap that laptop and take the shorter sentence!

[@fermitupoupon1754]

So you make sure the HDDs you use have glass platters, and put a solenoid in them to shatter the platters. The solenoid is tiny, looks like a regular part of the drive mechanism on x-ray, and if you mount it solidly it wouldn't be able to puncture the shell of the drive. Especially in a laptop situation you could just short the batteries through the solenoid, or just use a tiny mains powered solenoid in a data centre. It doesn't need to have a lot of force just drive a wedge into the edge of the platters. No need for explosives or anything dangerous. No booby trapping charges, and no recoverable data.

You should probably actually try learning how things work instead of just saying that to people who have. I have a lot of experience melting down hard drives and casting parts with the aluminum, and let me tell you, you're completely underestimating the thermal conductivity/heat capacity of aluminum. If you want to melt even the very edge of one of those hard drive cases, you have to get the entire thing up to right below that temperature. No matter how much heat you put into it, the rest of the case will just sink all that heat away from that edge and the hard drive will end up heating up very uniformly.

[@Stoney3K]

Are there even commercial systems that facilitate data self-destruction, for example in organisations that work with data that highly sensitive to theft or espionage?

Mount the cabinet over a large metal shredder with an hydraulic follwer plate to push it down into the shredder to keep it from popping out and surviving the shredding. Have the shredder dump it's contents after shredding into a blast furnace. Blast furnace should be fitted with an actual solid rocket fuel rocket engine, firing into a partially enclosed burn chamber, at no less than 5000 degrees. Have the rocket blast burn the contents and vent the gasses, fire, and fried hard drive particles out a long tube to blast the bits into an ash cloud that floats away in the breeze.

Heck, you could even maybe just mould a case from thermite itself, or mix it into the 3D printing filament if you're brave enough to risk it in the printer.

[@evknucklehead]

@@markpenrice6253 While most thermite variants probably would not ignite in a 3D Printer due to the relatively low temperatures involved, you run into other potential problems with the printed object, as having the wrong blend of thermite components to filament components would affect the ability to ignite the blend, and the thermite components themselves will likely affect the adhesion of the filament to itself, making the printed object fall apart too easily to be used for the mechanical stresses in a typical hard drive. Another thing to consider is that thermite itself is not a material, it's a blend of materials consisting of a fuel (usually aluminum due to its relatively low cost balanced with its high reactivity) and an oxide (Iron Oxide variants are most common, but not the only oxide used depending on what the goal of the thermite reaction is). By its nature, thermite works best as a powder, and really can't be combined into a solid object without some kind of binding agent. Then again, there are some versions of thermite that include a binding agent as part of their composition, such as the Magnesium/Teflon/Viton blend commonly used in decoy flares (the kind used to confuse IR-guided ["heat-seeking"] missiles) since the 1950's. While still not a perfect solution, due to Teflon and Viton's elasticity, it's probably more viable than some of the other options out there.

Using thermate with the close open space available inside I'd make 2 copper plated shaped charges to cut through the plates and scatter the bits.

More than happy to add the 1,000th like. Great presentation

He could have use flux to increase the burn time or he could use tungsten trioxide or boron trioxide, the tungsten produces the hottest thermite reaction and the boron is the most energetic and the most explosive

[@jryanburnette]

It needs a six foot metal enclosure with two feet of space inside and holes for the wires and such that can contain the blast.

Bring drive to volcano, drop in lava, data gone

Secret evil super villain base suspended over active volcano... Nice!

[@vcokltfre]

That would be pretty cool

17:05 What if you added an oxydizer (like KNO3) to the slurry so you had two reactions going at the same time? Something to help the wet portion be consumed as well?

they should watch the (now 7 years old) defcon talk "And That's How I Lost My Other Eye...Explorations in Data Destruction"

One wonders if you could just inject a highly abrasive powder in to the drive while it was spinning and just scratch it up enough to make it unreadable.

[@muha0644]

you could just get a huge bucket, fill in with thermate, bury the drives there (with the cables in) and when things go south you melt them all at once

[@StephenOwen]

Use the thermite with a plug of iron to create your own mini explosively formed penetrator to shatter the disk! Or, place your thermate charges on top of the disk, or drill out some of the center of the spindle to place some inside?

> 60 seconds to completion > a hot, New York minute

[@MichaelMacGyver]

kanthal wire (or something similar) to heat the platters past their curie point?

[@chadpunte1731]

Any liquid that hardens stronger than aluminum that also isn't removable by a solvent that doesn't react with aluminum would work. Nothing comes to mind except perhaps some sort of impregnated cement.

[@HaploidCell]

Hi. didn't you say you had 2 racks of destruction material per 1 rack of hard drive? Like, wouldn't that double the amount of thermite? Plus, the top-down method might work if the hard drive's cover wasn't that thick, or not there at all, or already part of the thermite container on top. The only problem then would be a reliable seal that wouldn't open during normal operation.
