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.

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