Nice. Still the problem with more current drives is the extreme data density in comparison to previous generations and thus the low tolerances during the process. In practise you would probably need to scan all the whole platters anyways as you don't really know where the file is and also the raw data might have been written over several ones in paralell to increase read/write speed (or so I assume).

True, and you're not going to get the data off with a simple Rpi, but the concept should still work. The company I mentioned recovers data from crashed drives all the time for $1k or so, they'd be able to give it a good go.

The reason I think the Ironkey guy has a better chance is mostly because a) He already has the device b) It is not damaged and c) the guy (presumably) already has enough money to fund the costly effort.

As for the technique, I was thinking about maybe using a SEM to recover either the "access password" or the internal encryption key + separately dump the flash memory (which I assume is a regular one). Something like this:

https://www.cl.cam.ac.uk/~sps32/cardis2016_sem.pdf
Possible. Some of these devices do have anti-tamper that will shatter the chip if you try to pry it or stuff like that. Still we're taking a budget of ~100 million to crack it which is well within the above paper's recommendation of "just buy a fucking ion mill and 3d the state of the chip". The fact he hasn't done something like this makes me wonder if it's all a bullshit story.

Quote
P.S.: Or maybe just dump the contents of the main flash chip and try to brute force the encryption key IF it is derived from the "access password".

I'm guessing the anti-tamper options will limit this. Then again even if the device is set back to zero there might be residual info to reconstruct the data. This is why the military grade ones literally explode. We are talking a budget of 100m to break it, and every safe is rated not to keep your data secure forever but as a function of "time and tools". He should at least be able to get to the "copy the data and brute the key" level with current tech.

Which goes to show that Bitcoin needs to be taken very seriously. "Be your own bank" is tough. If you're not organized, not backing up your stuff, not taking such things seriously, Bitcoin's going to bite you in ways you never expect. It's going to mess with your head and even drive you insane. Same goes for any of us. Remember to always safely keep backups of your paper wallets and seeds, and make sure you clearly remember your passphrases and PINs. Periodically check to verify that you actually have access to your coins, this will refresh your neurons. Keep your keys away from online devices. Never take your PC/mobile to the repair shop when you have crypto in it (which you shouldn't have in there anyway).

Indeed. The concept of "bit rot" is a problem, as is finding tools to be able to read older media. Try finding a 7 track magnetic tape drive :-)

After so many years of being buried under so much organic garbage, the chances of him finding the HDD and being able to extract the data are very slim. Still, an HDD is supposed to be a sealed container, although I believe there's usually a "breather" hole somewhere on the case, don't know what it's for, maybe to equalize pressure. If that's the case, and garbage juices and moisture got in though that, it's pretty much gone I guess...

Yeah, possibly. It certainly would not be an easy recovery but 250 million allows a lot of tools to work on it.

Quote
$250 million is a lot of money though, and can get things moving. If he manages to find the HDD, he should pledge to give a very generous percentage of that to anyone who can extract the wallet.

Good luck to him, he's going to need it, especially if he's unsuccessful.

And that is a big problem with this thing and the IronKey item: Anyone attempting recovery would know that a slip or error would result in wiping a quarter of a billion dollars of value off the earth, with the resulting "unhappiness" of whatever syndicate was funding the job. Forever you would have the question "maybe he got the key and is just not telling us" hanging over your head. (Yes, you could always check the public balance, but still people get weird when serious $$$ is on the line)

Even a simple task like replacing a USB port on a Trezor would be exceptionally complicated with that much $$$ on the line. It would be like walking a curb next to a street vs walking a curb over a river of lava.

What kind of hack do you use to read the platters in analog mode? Firmware mod or you do attach some gadget directly to the head controller and dump the analog data of all the surface for post processing? Asking for a friend Tongue

For SMD, Shugart 1000, MFM and ESDI drives the raw signal is right there on the connectors, the controller does the a/d and sampling. This is why some controller cards are much better at reading disks than others. Degraded servo tracks on non-stepper motor drives are usually the problem here.

For IDE and up you do have to do a bit of surface mounted troubleshooting to find the head output from the Op-Amps but it's do-able. Now the professionals will open the disk in a clean room then remove the platters and read them with custom heads. Also remember you don't have to get the whole disk you just need to find the file of the wallet.dat. Even part of it would go a long way, and with things like a 256 bit ECC code you can probably compute out the missing bits with a lot of CPU power.

I like screwing with this stuff, keeps me out of trouble. The ironkey would be a lot harder IMO:

That poor slob in Britain is still trying to get permission to search the landfill for his bitcoins. Worth 250 million.

I can't think about how much that could wreck someone's life.

Even if he were to find the computer, the hard drive is probably way beyond any humanly possible recovery.

He better go to some therapy that helps him let it go...

The Ironkey guy has a better chance... even if I don't fully trust his story.

Eh, it's possible. If it was a glass/ceramic disk then the data can be recovered. Remember that OnTrak recovered data from a disk that came down through the fireball of Columbia and spent a few weeks in a swamp.

I've been doing some data recovery on older drives, the power of a Raspberry Pi to read the tracks in analog mode and tease out the data is stunning.

Meantime. Fed money printers go brrrrrrrrrrrrrrrrrrr

BREAKING: Financial powerhouse Goldman Sachs to offer #crypto custody as early as 2021!

https://www.coindesk.com/goldman-sachs-to-enter-crypto-market-soon-with-custody-play-source


Wait... Crypto custody is a case of not-your-keys, right?

and like it or not it is how mass adoption is going to occur.


My thoughts are governments will start to prevent you from holding coins in your own wallets and buy 'token'

btc from companies like goldman's sachs.

And that is exactly when I cash out.

Hm. 2.45 bitcoins will get me a 10/10 Beechcraft Bonanza with a new engine....



I thought we were getting helicopters?
I don't know how to fly a helicopter. I can fly a Beech.

I don't know, that definitely makes me go "hmmmmmmmm"

Looks like CNN is back on Bitcoin being amazing again. "Ol'e George is back on top!"

40k again!



633  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: January 14, 2021, 01:54:10 PM
Meantime looks like 39k time.

eToro are facing a liquidity crunch, literally running out of Bitcoin to sell

Quote
The unprecedented demand for crypto, coupled with limited liquidity, presents challenges to our ability to support BUY orders over the weekend.

#stronghands
There is no "running out" of bitcoin. If they need one they can deliver a new Lambo to my house and I'll send them one for their users.

So simple to do instead of all that "temporarily increase supply to meet demand" stuff.....

Man things are going well in Bitcoin land. But we're still over 10,000 pages behind the coin. Need to shitpost a lot more....

Hey look bitcoin is at 37400. That's nice.

Boobs:

She likely was. But also troubled. I can remember intense fights between my parents when i was a boy and she did beat me up like a man a couple of times.
Before going deeper into private memories now, i better stop here.

*hug*

In other news, number seems to be going up. We need to break $40k ASAP. Now that I'm (probably) COVID-free, I need to see some action. Come on, Bitcoin, do something!
The Times should write a retraction and instead say that all ironkeys should be back-doored so that stupid people can ask to get their files and keys back. The example now has little to nothing to do with bitcoin.

Sorry if I am a bit focused on this, but I hate misinformation that pulls on heartstrings to do the wrong thing.

Thnx for the explanation -- wasn't familiar with Ironkey..     

I remember they had models with explosives in them to blow the chip apart, but that was for govt goodies. Still, the problem isn't bitcoin it's this guy storing it on an ironkey. Could have been a word document with his mothers' priceless recipes. So they article is crap, should he be able to get his bitcoin by whining a lot?

Fuck em.
