Cyberpunk 2077 Gig - Hacking the Hacker
When you arrive, the El Capitan fixer will tell you that he needs you to sabotage a 6th Street hideout and kill someone named Lucius. Head up the elevator marked with the yellow objective marker and go up to the 19th Apartments floor. Kill the two guards right outside the elevator and proceed forward.
Down the stairs is another enemy to take out. Slowly make your way through the first floor, either silently taking enemies out or going in guns blazing, to reach the staircase on the far left side of the floor. Be sure to loot everything in sight here as well as there is plenty to find. Go up the stairs, take out all of the enemies on the second floor of this hideout, and then loot everything. When you're ready, install the malware on the computer
If you've killed everyone in the hideout, you will have completed the optional objective, Kill Lucius, as well and El Capitan will pay you more for doing so. If you have Level 6 Technical Ability, go to the room to the left of the computer and go through the door to find a door locked behind Level 6 Technical Ability. You will find the Legendary Crafting Spec for the RT-46 Burya in a box in here.
After you've looted all you want, leave this hideout, talk to El Capitan, and go to the drop point at the bottom of the building to complete this gig.
