Early in the game you'll get a quest to check on a tenant "making bombs" in SANS LUXE apartments.
Lock picking the first apartment on the left (#6) will open a small room filled with computers and a weird hacker type called Satoshii.
He will hand you a suitcase between some gibberish techno-jargon.
Simply don't open the suitcase until you meet him again later in the game to get this achievements. The contents of the suitcase (for me) was 41 scraps.
