This tutorial will explain how you can get the Hello You trophy in Sly 3: Honor Among Thieves (2024) on PS5 and PS4.
In order to unlock this, you need to “receive a message from a computer in the Ancestors’ Gauntlet job.”
Use the following video as a reference:
You will find the computer near the end of the Ancestors’ Gauntlet, located to the right of the painting.
You need to stand close to it and then use your binoculars to zoom in. The trophy should unlock when you see Hello World on the screen.
