BreachBlocker Unlocker

Hopper the Detective

When Sir BreachBlocker is captured, Hopper senses an opportunity: the last key to the stolen AoC charity funds is hidden somewhere on Sir BreachBlocker’s seized phone.
The device looks innocent enough: a Hopflix streaming app, a banking app, messages, photos, and settings. But nothing about this op is innocent. Hopper must somehow pivot into the linked bank account, and, outsmarting the layered authentication around it, he can wrest control of the funds before King Malhare’s cronies move them for good. If he succeeds, The Best Festival Company is saved; if he fails, the story of “Colonel Panic” ends in quiet disgrace, erased like so many secrets before.

  Initial Access.

This Side Quest is unlocked by finding the Side Quest key in Advent of Cyber Day 21. Once you’ve recovered that key, visit MACHINE_IP:1997 and enter it to unlock Hopper’s challenge. From there, your mission is simple to state and hard to execute: break into Sir BreachBlocker’s phone, bypass all authentication, and recover the final key needed to release the funds for The Best Festival Company.
