From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

unfortunately, mass attacks happen all the time. if you ever had access to the authentication logs of an SSH server with an unfirewalled port 22 into the internet that has been running for a few months, you would see international IPs starting port scans and brute force attacks. there is always someone out there trying to hack random IPs. it's fucking wild west out there.
Yeah. I'd recommend using ssh keys and disabling password authentication whenever something is exposed to a public network
