SK-CERT CyberGame 2026: OSINT Challenges Writeup
A complete walkthrough of the SK-CERT CyberGame 2026 OSINT challenges across two distinct series. The Lore of the World series investigates the archived Hermitcraft Season 10 Minecraft world across five challenges - identifying MumboJumbo's starter base, decoding Grian's bureaucracy permit form, naming SmallishBeans' dog via world parsing, extracting precise XYZ coordinates from playerdata NBT files, and locating Rendog's GigaCorp facility by scanning entity data and decoding a ROT13 cipher. The Travellers series tracks a hacktivist group through four real-world geolocation challenges - identifying the Algonquin Centre for Construction Excellence in Ottawa, the Minsk-Arena in Belarus, the Sumavska 67a business district in Brno, and the Erbil Amphitheater in Iraq - then pinpointing the nearest island, building, nightclub, and cafe to each location using satellite imagery and local business data.
