/dev/sda is the whole raw disk - you typically don't want to directly interact with /dev/sda, unless you are partitioning or overwriting it. There are a few layers between that device and the files:

• raw disk - /dev/sda
• disk partition - /dev/sda1
• luks container - when unlocked, mapped to /dev/mapper/{name}
• ext4 filesystem inside the luks container, mounted somewhere like /mnt, /media, etc

You'll need to find where that ext4 filesystem is mounted, and run the chown command on that. You can run lsblkand see a tree of the above hierarchy, with the ext4 filesystem's mountpount shown in the right-hand column.

Friendly reminder that lemmy votes are public

I blocked hexbear and lemmygrad to stop the firehose of kremlin/beijing propaganda cluttering up my feed and that made my lemmy experience worlds better. There's only so many times you can read "special military operation" used unironically..

Get fucked, Russia.

The only legitimate commands for a non-root shell are sudo -i, exit, and echo "yee haw"

Anyone that uses "woke" as a pejorative really just wants to say the n-word instead, but don't think they can get away with it yet.

This is just an attack that attempts common username/password combinations on ssh, and the article even states that the worm is dime-a-dozen. Unless you have both password auth enabled and an available account with an easily guessable password (and if you have either you should change that), this is nothing to worry about, even with sshd available to the internet.

Sensationalist title.

If you aren't going to fully wipe your drive in horrible events like this, at the very least use shred instead of rm. rm simply removes references to the file in the filesystem, leaving the data behind on the disk until other data happens to be written there.

Do not ever allow data like that to exist on your machines. The law doesn't care how it got there.

Thank fucking god for the EU, for fighting for global digital rights where nobody else does.

One benefit of base 12 and base 60 over base 10 for everyday use with things like time is simple factorization. You can divide 12 hours evenly into halves, thirds, quarters, and sixths, and 60 minutes evenly into halves, thirds, quarters, fifths, sixths, tenths, etc. With base 10, you've just got halves and fifths.
