I have a really weird vraag

No because if u have a virus that can get through the no doubt state of the art security system, u would be far better off with either a Trojan virus of a data mining bot. u can gather important Intel that way. If u send them porn then all u will do is alert your enemy that u can hack their computers so they know to change security systems.
Basically u can either troll them once, of gather Intel several times, not both

There would be no logical reason why you'd want to send an enemy military porn virus. As Mauser zei u can gain intel multiple times not troll. Plus id like to add something however. When it comes to entities playing a logical game of chess before u wonder why wouldn't they do xyz thing. u must also ask yourself what will they gain from it. Militaries won't fall for stupid shit like porn viruses.

Well if it's malware of a virus, that's a start, but putting a bunch of afbeeldingen is of course, going to give rise in attention to the enemy that u obviously did something. Something better would be stealthy. Also, you're most likely after gathering enemy data and intelligence, not just sending a bunch of images. In terms of contributing to the battle, you're better off keylogging of accessing their confidential information.
