Nifty. I couldn't see a practical use for myself but, it's cool none the less.

Very useful for getting any sort of private data through an airport that does not respect privacy. For example any US airport...

No it isn't. It will be treated like any other drive where encryption is nothing new. In fact, to look for a text file and then make something accessible means it is likely much easier to detect that something is off about it than regular encryption that just looks like random data. Whether it tries to hide it's true storage capacity or boots its own internal OS to present storage, people often think they're being clever when really they're just making themselves stand out.

Do you think TSA/CBP is going to check the flash data lines to see if the MCU is scanning the flash internally?

This isn't a standard USB flash controller... You would need to break the casing and physically probe it to figure out that something was off as far as I can tell. It's not like the MCU broadcasts that it is scanning to the USB port.

You would have to be hitting the stick pretty hard, not just a normal file scan to notice the timing being slightly too long in a small portion of the scans. The bigger problem would be that the flash drive would be brand-recognizable if it ends up being mass produced that they might auto-confiscate it, and of course the default file that it searches for being known.

If I got it right, you could easily detect this drive by just creating password.txt. as the article says it creation is intercepted and skipped. Hence if there is no password.txt afterwards, you know what you're dealing with. Still, you have to know this AND care.

It looks for a string "password:xyz" bring written to any file, where xyz is the password. If you get the password wrong it'll just write the file normally

Ah okay, so then I retract my statement and better my reading-skills 😁

No worries, I had to read stuff outside of the articles to get that information
