That's the premise of the YoRHa Betrayers side quest, which is bestowed by checking your email and receiving a confidential mission details message. The message starting the YoRHA Betrayers quest will only appear after the Goliath event when you access the flooded ruins. You can grab this mission at any access point after that event. After reading the email message and starting the quest, three different map locations will be marked where the rogue androids could possibly be hiding out. The idea is to detain them, find out why they went rogue, and recover the stolen supplies.
