Isn't irradiating really a feasible thing?

no. that will alter data, not destroy

Cory Goodman if you go that route there is no such thing as destruction of data or anything, everything is technically just altered but yeah for all practical realistic purposes that can easily destroy it

how fitting

Cory Goodman Doesn't make any sense but ok

tizoro3, watch the video, it'll make sense.

Then you have a problem with freezing attacks.

@@privateger considering that you would need to flip a switch anyway you could just flip the powerswitch to shut everything off.

@@kfftfuftur You uh...do know what a freezing attack is, right?

@@privateger Volatile memory is easier and faster to overwrite with random data to wipe it if there is a security mechanism to trigger it. They can freeze attack all they want, because all you find on the memory is garbage data.

@@Stoney3K You most probably do not have such a security mechanism set up and probably won't have the time to trigger it anyway.

thats actually quite good information to know

On the nose! I'd also encase it for a shaped charge. Cut through the discs.

There are dozens of videos here on youtube that contradict what you say here. They all light the top of the thermite charge. It all turns into one very hot charge of liquid iron. Where you light it really doesn't matter.

@@ilikepie1974 Right... because you will certainly need to use thermite one day. Life's just a Bond film for you, ain't it?

@@riftalope traditional method would be use a flower pot, light through the drainage hole.

Pretty sure even the small ones wouldn't fit into a 1U rack. Or pass the seismic sensor requirement. Or the not harming other equipment requirement. Or the...

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.

evknucklehead Don't forget not harming the meat equipment

isn't 50kg the critical mass? good luck getting that into 1U :D

just grind your own disk into powder and thermite the powder

Blazing fast data delivery

will be getting quite hot in there. On a more serious note: will the reaction consume environmental oxygen?

Agreed I wish he had tested thermite with SSD, I mean come on....

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. Almost none of the methods he presented would fulfil data erasure standards (exceptions being thermite if the conductivity brought the entire platter over curie temperature and possibly explosion-welded platters).

Thermite against an SSD would be an easy win, there's no challenge. Just plastic, silicon, and tiny pieces of metals.

I would walk with a light step there. Not much is know about that, I would assume yes. However there is no knowing for sure.

@@MauranKilom It really is nuts how well these things retain information. like they can bring data out of a thing that barely resembles a disk anymore. im interested in reading how these things go in the long term, like for example celuloid film breaks down within decades under normal conditions, magnetic film on the other hand is rock solid. i wonder where this type of stuff or even SSDs falls in

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...

Where's the fun in that?

@Serenity Laboratories if you want to *destroy* the data, you just destroy the key as well. When the alternative is termite, you don't think about potentially saving data anymore, you just get rid of it

Wasnt there a malware a while back that intentionally ripped the drives apart by shaking them violently?

those were uranium centrifuges

if the data on the drive would make you considered a "national security threat", booby trap charges are better.

I am wondering if a pneumatic system that could be tripped by a motion sensor, like on a door sealed shut couldn't solve that, when they raid they go in every entry they can....

+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!

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.

RedPark Don't ask questions when you're on the internet. It makes you look really really stupid.

tizoro3 I thought the objective of a question was to get an answer. Is any question stupid when you don't know the answer and want to further your knowledge. To me advancing your knowledge is a very wise choice. Asking a question so that I could further my knowledge was a smart thing to do, because I now have more knowledge. Knowledge is power in this world of technology and information. So ask your self, is making your self more powerful stupid?

I was thinking along the same lines, going around the entire rack sounds a bit excessive. I thing that would be more of a lay out matter though.

Where do you purchase (or power) an induction blanket that can reach those kinds of temps? Typically they stop at 400f...

If you are really serious you use powerful electromagnets to degause the platter and if you have time run the gutman protocol on it

@@TheSethcoleman I suspect its more about the number of joules delivered than about the number of farenheits.

@@mjouwbuis in resistive or inductive heating there going to be a correlation. Regardless of the unit of measure what the comment is proposing isn't possible.

You have to physically destroy the drive platters to prevent forensic recovery. Sure the drive would be broken but the information would still be there.

Have you ever seen glass discs spin at ridiculous speeds? Glass disintegrates relatively spectacularly when spun fast enough.

@@insu_na Glass disks can be takens care of easily. The reason Al dicks are used is because they are cheaper, more common, and harder to destroy.

nori Learn how things work then you'll understand.

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.

Bart Bols the reason they are physically destroying the drives in because there is always a way to recover data, as long as the physical form exists

Jesus Christ a deadmans switch can very well be something that physically destroys the drives. there are plenty of examples how to do this on a certain pirate youtube channel.

Software that cleans the drive? Meaning you want to just zero out the drives? That would take much longer to do than it would for anyone to figure out that it's a bluff.

Hard drives RECORD data. "File deletion" utilities do not destroy deleted files, and 'wipe' utilities do not 'cap it all off' either. Originally written data can be recovered if the drive platters are available and still flat, PERIOD.

If you have 10GB drives then you could overwrite the entire disk with trash in 1 minute. I understand that writing all zeros to the drive can leave small differences in each magnetic bit that an analogue reader could bring back some of the original data. However, I think it could be possible to install hacked firmware such that it would write random analogue data and no guesses could be made as to the original data.

That is amazing BS. I can tell you that even an accidental explosive dispersion of gas through a fire protection system did nothing to live equipment. If you don’t correctly secure your racks in place you can tilt them and lock drives, yes. But not destroy platters ‘due to sound’.

the aluminium case will react with naoh making it even hotter and more reactive.

But will it destroy it in sixty seconds?

@@wichitawwojak3786 If you kept it permanently molten, probably, but that's a lot of energy use

No. The drive 'dies'. ALL of 'the data' is not. Some will remain. Any platter surface not destroyed can be read. It does not require reading all of it.

The rest of the cases are typically aluminum too, meaning you're still wasting a bunch of your energy heating up the case instead of the platters.

@@evknucklehead ... 3D print a whole new case and transplant the guts? Given that if you're going to consider packing the drive internals with thermite you're probably going to be working in a clean room and/or accepting the risk of a dust-induced head crash anyway... 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.

@@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.

I know right

+MrCarrot14 the point is that the drive has to be in the computer (he says server but same difference) and that the process would be linked to a panic button or a intruder alarm and that the rest of the computer is useable/fixable or at least the damage contained inside the computer

that doesnt work with aluminum

Yes, that sounds super practical for your 10000 drive datacentre
