>If you're using off-the-shelf "hidden" encrypted volume schemes, you're not going to be evading state-level adversaries;

This would evade 99% of them.

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

I once had a police officer literally raid my room for drugs during a massive party we were throwing in university, for example.

They took everything. They found everything. Everything except for the $1,000 piece of drug paraphernalia I had sitting right out in open view in the middle of the apartment... the Volcano vaporizer.

It didn't look like anything they had seen before so they didn't think anything of it.

Same would be true with this USB drive in 99% of border crossing privacy invasions... plug in USB, ask for password, read it/copy it/whatever... they're not taking it apart and performing open heart surgery on a $5 USB drive at the border.

They might throw it out... or keep it or something... sure... but in general... this is a hell of a lot better than a regular USB drive imho.

This is self-soothing, not a real security plan. It doesn't matter how competent a security agency is, because there's a whole ecosystem of vendors selling into that space; knowledge of how to attack encrypted disks like this is outsourced, and, importantly, those firms have incentives to mop up even random stuff like this, because vendors will be selected in part based on lists of how many different circumvention and privacy tools they can detect.

The state-level threat isn't just about the direct employees' competence. They also have the funding to purchase tools made by people who really know what they are doing. Think of things like Pegasus spyware or Darksword iPhone hacking.

I can believe that a keystone cop wouldn't know the difference between a bong and a flower vase, but border crossing guards will know a USB drive when they see one and pass a copy of it to someone who knows what they are doing.

You will miss your government's incompetence when they start rectifying these failures. I know I do.

They are the tyrants who oppress us with a clean conscience. They never rest and have infinite money. Their occasional episodes of bumbling incompetence is the only respite, but those won't last. Especially now with AI to think for them.

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.

You are conflating „state level actor” with „police level action”.

There is a world of difference if you get searched by your local police and a country level agency.

There are military units dealing with forensic investigations they have 100x or 1000x more budget and much smarter people.

But they don’t care about some drug dealers. They don’t waste time on silly stuff.

Anyone using forensic software can dump an image of your entire drive including all partitions, byte for byte copy. Just because you got away with being careless once doesn't mean this will work every time. If you don't want your files to be copied in encrypted or plain unencrypted form, don't bring them with you. You're better off re-downloading them over the web at that point.

Trying to keep data on a USB drive hidden long term is a losing game is the thing.

If you're intercepted with anything of value what you want is to rapidly destroy it.

This was the big problem I found when I was trying to figure out a secure way use Yubikeys: they're both long term unreliable, and short term impossible to wipe or destroy fast enough.

Literally a printout of 1 time passwords has better security properties in an adversarial situation.

For a storage device what you want isn't a secure store, what you want is a pin pull or switch which wipes it instantly.
