So after another couple of hours looking for that attack drone eximus, I finally saw and scanned two of them (giving me the 3 scans).

In order to help other players I'll put here the mecanics I deduced from this long boring farm :

I did Palus survival, I had a lot of eximus there and a lot of fusion MOAs but 0 attack drone eximus.

I did Narcissus exterminate and had 3-4 eximus everytime but, ONLY TECHS AND FUSION MOAs. I did the mission more than 25 times so I doubt another enemy can be eximus on this mission (I might be wrong but from my personal experience, all the eximus you'll meet will be those 2 enemies). The mission where I got 4 fusion MOAs eximus (2 then 2) was the best display of my theory on this mission.

And finally, I did the other exterminate mission on pluto (I discovered after the Narcissus farm) named Acheron, and the very first try there I got an attack drone eximus! Then I did it two more times to have a 2nd one. So I highly recommand this mission for whoever wants these 3 scans.

Thx to Ninjaslippers for the help
