On January 18-29, 2021, the CrowdStrike® Intelligence Advanced Research team invites you to go head-to-head with three unique adversaries during our first-ever CrowdStrike Intelligence Adversary Quest.

Register now for this exciting cybersecurity journey, where you’ll be able to track CATAPULT SPIDER, a ransomware adversary with an altcoin passion, save source code repositories from SPACE JACKAL hacktivists, and dive deeply into PROTECTIVE PENGUIN’s ambitions to hide in the Antarctic.

How the Quest Is Designed

The Adversary Quest features one track for each adversary and includes four challenges covering topics such as OSINT research, packet analysis, reverse engineering and binary exploitation. The game is open to individual players (no teams) and is designed to be an enjoyable experience for security enthusiasts of all skill levels. CrowdStrike’s Adversary Quest will run for a total of 11 days, giving everyone the opportunity to participate on their own time. Last but not least, we’ll have some cool swag for the players with the top scores.
