How to unlock the Intruder achievement in METAL GEAR SOLID V: THE PHANTOM PAIN - Definitive Guide
Currently getting this to work can be pretty janky. You first need to get your own FOB, but the game has been known to freeze when you purchase it (during the tutorial). So what you do is load the game up in offline mode, turn online mode on from the pause menu, then purchase an FOB. This tends to get around it.
After this, go to the Aerial Command Center and open up the Missions tab on your iDroid. Pick FOB Missions, and choose a base to invade. The achievement pops as soon as you commence the mission, so no pressure to win (they're actually pretty hard).
As of the writing of this guide, these bases default to people your rank. It's entirely possible you could find an empty FoB to attack.
Thanks.
Online FOBs unlock after mission 22, which is basically a tutorial for this mode.
After this, FOBs will appear under the Mission tab on your iDroid. In here, select someone you want to infiltrate. When the infiltration starts, you should already get the trophy, so win or loss doesn't matter (I failed my infiltration, but still got the trophy already).
“Infiltration” FOB missions take place when you invade another player’s forward operating base. These missions can be commenced through the iDroid’s FOB Mission selection screen. They will only become available once you have completed mission 22, "Retake the Platform" (which acts a tutorial for FOB missions).
Once you’ve completed this mission and can access the FOB mission selection screen, simply choose a player’s base to invade and the achievement will unlock after the sortie prep screen. This means that you don’t actually have to complete the mission at all. Keep in mind though, you will definitely need an online connection to earn this achievement.

You will receive the trophy as soon as you land on someone else's base.
Infiltration tip - Bring firearms to destroy security cameras and flying drones of guards.
