Hacking Device is a preparation mission for The Black Box File, featured in Grand Theft Auto Online as part of Agents of Sabotage update.
Description[]
After accepting the mission, Jodi will reveal that the targeted Cargo Plane, which is supposedly being remotely used by the International Affairs Agency for smuggling, has been cleared for a landing at the LSIA. In order to reroute the Cargo Plane, Jodi suggests the player to go secure a hacking device from a FIB endorsed cybersecurity firm.
Arriving at the location, the player must get access to the building roof by finding a ladder, get pass through the armed goons on the terrace and locate the hacking device.
Once the item is collected, the player must head to LSIA and attach the hacking device to an electrical box at the top of the LSIA control tower. The control tower is guarded by police officers and security cameras, and the player is advised to avoid their cone of vision.

The player must climb the ladder and interact with the electrical box on top of the tower in order to plant the device for the final operation. Once the objective is completed, they are free to leave the area and complete the mission.
