If an attacker has physical access to your computer, could he modify an encrypted file as such that when you move the file to another computer and decrypt it there this new computer which you intended to use to safely decrypt your file will be infected?
I'm interested if this is possible for
LUKS / truecrypt
Veracrypt
PLAIN dm-crypt
which are all implemented in zuluCrypt.
If that is not the case would it be possible with encrypted *.odt files?
