Illium: Liara: System Hacking

Nathan Garvin

This mission can be started by talking to Liara on Illium, which you can only access after completing the core mission on Horizon. Just be sure not to start [Lair of the Shadow Broker] before completing this mission, otherwise it’ll autocomplete… although you’ll still gain XP for it.

(1 of 3) To appease Liara, you'll need to seek out several Secure Terminals,

In any event, you’ll be tasked with hacking three terminals, then after hacking each terminal you’ll need to track down another terminal made vulnerable by your recent hacking. You’ll get a distance readout giving you a general sense of how close you are to the vulnerable terminal… or you can just follow the directions, below:

Targets Location
Secure Station 1: Along the wall northwest of the Gateway Personal Defense kiosk.
Vulnerable System 1: Southeast of the Memories of Illium kiosk.
Secure Station 2: A wall monitor east of the Gateway Personal Defense kiosk.
Vulnerable System 2: North of the Tracking Office.
Secure Station 3: A wall monitor north of the Tracking Office.
Vulnerable System 3: Southeast of the Tracking Office, northeast of the Baria Frontiers kiosk.

Hack all the terminals and find the vulnerable system tied to it, then return to Liara to complete the mission and earn 2,000 credits.

At this point, this mission will apparently go dormant, but all you need to do is talk to Liara again, at which point the mission will continue under the name Illium: Liara: The Observer.
