Targeting Linux distributions is even less likely because unlike Windows or MacOS there is no “official” viewer for a kind of document, being image, video, text, etc but rather only the one that the distribution picked but that even during the installation process the user might ignore or replace. So the attack on the media would have to work for any viewer which seems basically impossible.
Technically possible yes but practically impossible at scale, it would have to be targeting a specific user and then it’s a totally different situation.





In theory maybe but in practice documents viewers and editors are rather foolproof as they read content but they don’t execute. The file formats are specifically defined. Also each distribution might have a different default viewer per file format and the user might install a different default, so it’s very hard to target, unlike for other OSes with a well known default.
