I don't see anything particular about Linux and Unix systems regarding such malware. Non-Microsoft focused answers like this one can be adopted for other operating systems.
- Behave like an educated and conscious computer user.
- Do not hand your devices to others, always keep them with you or safely locked away.
- Encrypt your backups and make sure that nobody else can.
- Keep your installed software up to date on a daily basis. Use kernel live patching if you can, some distributions offer it for free and update your kernel on an hourly basis if there are updates available. Reboot regularly.
- Follow the principles of least privilege and trust no one as best as you can.
