CHALLENGE NAME
The Hidden Grave Marker
A watcher's device in Hollow Mere village went silent—refused to wake, refused to speak. When Brynn examined its memory, she found something that shouldn't exist: a folder named .data_gsc98647a3, hidden like a grave marker in a forgotten cemetery. No legitimate tool creates such cryptic names. This is an artifact, a fingerprint left by something malicious that passed through. The folder itself is a clue—a signature in the digital earth. Brynn must investigate this strange naming pattern through malware records and shadow-threat databases, identify which tool carves such markers into infected systems, trace it to the group that wields this particular blade, and uncover the infrastructure behind this digital burial. The dead folder speaks, if you know how to listen.

CHALLENGE NAME
The Azure Deception
Shortly after the Door Without Handles began moving, someone sent Brynn a taunting message through the council's communication channels. It appeared to come from Microsoft's own security team—the address read [email protected]—but the words dripped with mockery: "It looks like you fell for it… Again. Not every onmicrosoft.com is official ;)". The domain seemed legitimate at first—onmicrosoft.com is genuine Microsoft territory—yet Brynn knows deception when she sees it. Someone is wearing a trusted mask. She must investigate this exact address through shadow-intelligence archives, identify which ghost organization has weaponized this Microsoft domain in past hauntings, and determine which named operation previously used this specific false identity to breach their victims. Even the most official-looking doors can lead to hollowed places.Flag Format: HTB{Operation_Name} Example (Fictional): HTB{Operation_Midnight} Important: Use underscore _ between words Capitalize first letter of each word Include "Operation" if it's part of the name
