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.

Ignore the idiot posting about this RAT.
If you want to secure your Linux system, use ClamAV, a local firewall like UFW or even opensnitch for a start. Also use your head when adding apps to your system. Stick to the official repos from your distro. Things like Arch's AUR, random PPAs in Ubuntu and any random github project are going to be much riskier by their very nature so act accordingly.
If you need to risky stuff, do it a VM and network that guest into a private internal network that can only exit over a companion PFSense VM that is dual homed to the regular LAN and the private internal network. Take a snapshot of the risky guest before you use it in a session and when you are done, roll back to your clean snapshot.
Store your passwords in something like Keepass(strong master password!) and then use syncthing to push copies of the database to at least one other box locally or in the cloud if you really have to.
