The Story
Enter NIGHTFALL
NIGHTFALL is a story driven cyber investigation in which a routine narcotics case leads players from a seized phone into a hidden dark web marketplace, through its people and infrastructure, and ultimately toward the identification of the individual controlling the entire operation.
Jointly organized by Kerala Police CyberDome and Beagle Security at c0c0n XIX, DomeCTF 2026 turns that narrative into hands on challenges — forensic clues, live systems, and the pressure of a case that keeps unfolding.
Every flag is a lead. Every service is a node in the network. Trace vendors, map infrastructure, and connect the dots before the operator vanishes into the dark.
Compete solo or as a team, online at the venue, and see who can close the case with the highest score on the board.
📅 October 9th–10th | Grand Hyatt, Kochi
