This achievement is part of the storyline you follow when working for Ryujin Industries. As you get into the later stages of it you learn that a mole inside the corporation has leaked info on a ‘Project Dominion’ to a competitor.
The mission immediately before this one involves a security sweep. It’s stealth based and can be a bit of a pain, so bear that in mind when doing this storyline. Once you’ve got the security sweep out of the way and identified the suspect, the mission for the achievement is relatively straightforward.
How you approach it is up to you, but the easiest way is to persuade Benjamin Bayu to allow you to enter the Seokguh Syndicate hideout peacefully. From there you can confront the suspect and deal with the situation as you see fit.
