Might as well be rot13. If you rented 8 MI300X's or the nvidia equivalent, I don't even think an unreasonably long password would matter. It should finish quickly enough that you would be upset with all of the money you have now wasted by having to commit to a month of utilization

If you need 8 MI300X's for a month to do ROT13, then you're doing it wrong.

Pegasus spyware operations cost something like $500k a pop, last I checked.

Can you check again and share where you're getting that number?

If you're using off-the-shelf "hidden" encrypted volume schemes, you're not going to be evading state-level adversaries; if you can find these projects and conveniently use them, state vendors can and will write scanners that find them. They're paid to do it; new detections are how they get to charge for maintenance and new versions. Then you're down to two issues: (1) Concealing an encrypted volume jacks suspicion w…

Given that the name defaults to "Phantomdrive" I have a hunch that it is not as fully nondescript as you are suggesting it ought to be.

Someone should write a disk formatting utility that randomizes the bits on your drive. Now you can claim that any encrypted drive (which just looks like pure noise if done correctly) is a drive that was just formatted.

Sounds a lot like stenography. https://github.com/dishather/steganodisk

The security track record of steganography is not great.

> If you're using off-the-shelf "hidden" encrypted volume schemes, you're not going to be evading state-level adversaries; I kinda assumed this was a solved problem now, up to the information-theoretic limit. Just create a FAT32 fs (for example), put some boring decoy files on it, and then unmount it. Traverse the FAT to map which blocks are in-use vs not-in-use, and use the not-in-use ones to store your encrypted da…

>This could be solved by bundling it with OSes by default.

Apple and Microsoft? I trust apple a bit more and MS none at all.

Linux is a bit different because the kernel is the OS, but only a small part of all its different packages. Also you'll have to watch it like a hawk because nation states will constantly try to compromise it.

Be careful in countries like UK which have laws requiring the decryption of any data they find. There are people sitting in jail because they couldn't decrypt the "random noise" on their computers.

There literally are not. Anyone competent enough to be an expert witness will be able to plainly explain to everyone else how statistical analysis obviously delinates the difference between truly random noise and an encrypted volume.

If there's a difference visible, that's a weakness in the encryption algorithm.

Encrypted data should be statistically indistinct from random noise.

It's an information theory thing. Everything in the ciphertext should be sitting at maximum entropy.

Loll, you have a lot of faith in the legal system that I do not. Expert witnesses are commonly full of shit.

That's kinda the defining characteristic of a state-level threat. They have all the money they could ever need. The reason Pegasus can charge that much is because there are people able and willing to pay that much.

It may have gotten cheaper

Most "state-level" adversaries are just high school dropouts working border jobs told to "investigate suspicious things".

I was arrested once and interrogated in great detail about how to access the data on a bluetooth usb dongle.

Just to say, I know what you mean.
