UK seized new powers starting today [including destroying Monero]
--Police will no longer be required to make an arrest before seizing crypto from a suspect.
--seize anything, such as written passwords, flash drives, or memory sticks
--destroy crypto assets, such as privacy coins, for the "public good", like Monero
--goes into effect today
This has the text copy-pasted from the official UK website, but without having to have your IP address literally connect to the official cybercrime division website, (ironically, we seized their text)
You type that password to that file on your machine daily. Nobody has to crack it. You get malware on your machine, they have the file and the passphrase. Your encryption scheme is no more secure against remote malware attacks than storing it in plain text.
I primarily use it on my phone so fingerprint. I rarely have to type it out. Plus i run DNS level malware and ad blockers, linux, and as much FOSS software as possible. I have no doubt it would be possible to get it, but its not a huge concern.
