I'm currently still running a dual boot on my desktop machine. Here's what it looks like:
- Linux Mint 19.2 is installed on its own, separate partition (sda1)
- So is a Windoze 7 system (sda2)
- My Linux /home folder with all of my private files is on a separate drive/partition (sdb1) that is LUKS/LVM encrypted
I'm particularly curious to know:
- what are the odds of compromising the integrity of my Linux system? Let's say I catch a keylogger trojan on the Win7 system - is it possible for said trojan to spy on my keystrokes under Linux as well, e.g. by implanting itself to the MBR or manipulating my Linux system (if, for some reason, it can read the Ext4 of sda1)?
- what are the odds of losing my private files on the encrypted drive? Let's say I catch a crypto trojan on the Win7 system - is it possible for said trojan to encrypt or, as some do, simply destroy my private data on sdb1? The Win7 system does not "speak" Ext4 and cannot get through the encryption, but could a trojan attack at the partition level, e.g. by encrypting or overwriting the entire partition with zeros?
- Are there any other horror scenarios I forgot and might run into?
