Scenario
Celestic Telecom provides services and connectivity for a large and varied set of customers. On Thursday, May 4 2023, Celestic Telecom noticed some odd behavior on their network and three of Celestic Telecom’s customers (Jubilife Water Purification, Snowpoint Transport, and Veilstone Power) also reported serious issues in their ICS/OT environments.
Players in this Capture the Flag activity will explore the network and host artifacts to discover the cause of these issues and help secure these companies and restore the functionality of their ICS/OT systems. Network traffic from May 4 across various subnets of Celestic’s networks has been ingested into Malcolm to aid in the player’s investigation.
This CTF also contains Security Foundations challenges which serve as introductory-level challenges on various security and ICS concepts, and though unrelated to the scenario, still award points!
