protection against ransomware
I've been surprised by recent reports of ransomware that specifically targets Linux computers. (See article at end of post.) I would think that Linux PCs would be far less vulnerable to ransomware because it would have to trick you into typing in your password to allow it to install. Is this correct? Linux-targeted ransomware cannot install unless the user permits it via typing in his password. Correct? I would thus think a huge protection against it would be to know your software sources. Install from the official repository, of possible. If not possible, at least know who your source is.
Another thing I'm doing is this. I keep a backup of all important files to a thumb drive that I don't keep plugged into my computer or anywhere else on the network. I don't even save my work to the internal hard drive. I have one thumb drive that I save my work to and keep plugged in. Then I use FreeFileSync periodically to back that thumb drive up to another one. That backup thumb drive only gets plugged in when I need to backup my main one. Otherwise, it stays safely in a special pouch away from the computer.
It does seem unlikely that I'll get attacked by ransomware. However, if I did, I could boot straight to Geparted on a DVD or thumb drive and then wipe the hard drive. Then I could install Kubuntu from scratch. If my files were encrypted on my main thumb drive, I could just format it and get my files back from my backup thumb drive.
This is what I know to do to protect against ransomware. If anyone knows of anything else I should do, please speak up. I used to work in a computer place that fixed Windows machines infected by ransomware. This type of malware is something I find particularly disgusting, not that any malware is good. I remember the frustration of customers and how violated they felt by these criminals. We were almost always able to save their machines, granted that was some years back. I hear ransomware nowadays has gotten even worse.
If there's anything else I should do besides what I'm already doing, I'm all ears. Maybe I should also do an occasional Clam scan for malware? I do have WINE installed on this PC, but I only run two Windows programs that way. I run a language dictionary named Ultralingua 6. I've been running that same version for years, and I trust the original source I bought it from years ago. I also run Treepad Business Edition. That's a note-taking program that I purchased from the legitimate source. It runs pretty well under WINE, though I don't use it anymore. I also run a few more programs under Windows 7 in VirtualBox. I know what you're thinking. Windows 7 isn't supported anymore with any security updates. However, I've got it locked down to not update, and I've blocked it from even accessing the Internet. I run a few old Windows programs under it whose sources I trust, as I bought them legitimately. I only run them occasionally, and neither these Windows apps nor Windows 7 are ever permitted to access the Internet.
I therefore think I'm protected pretty well. I use safe software sources. Most Kubuntu installs happen via the repositories, Snap, and Flathub. I do have a couple programs that I install via deb files. They're both proprietary applications that I bought from the legitimate seller. One is a screenwriting word processor named Fade In. The other is SoftMaker Office, which is an office suite made in Germany, and also purchased legitimately from them. I also use the donation-installer provided by the people who make FreeFileSync. Basically, if you make a donation to them, you get their donation install file that auto updates when a new version comes out.
I don't download or run any deb or other install files whose source I don't know, and I don't use any PPAs whose origin I don't know.
I've got Clam installed, but honestly I don't use it much. I welcome any other comments on keeping safe from ransomware, either in your *buntu OS itself, in WINE, or in VirtualBox, or any other system you might run on a Linux PC.
