Stealth-Cup:
Where Hackers Challenge Detection Systems For Thrill and Skill
Stealth-Cup is a research project that aims to benchmark intrusion detection systems by combining red teaming realism with the repeatability of adversary simulations. Additionally, it serves as a valuable educational platform for penetration testers.
Up to ten teams will attempt to hack into the network as stealthily as possible and achieve intermediate goals (e.g. exfiltration, destruction). The team with the fewest severe detections wins! There will be an overall winner, as well as separate IT and OT cup winners. Hackers will receive direct feedback on detections and can adapt evasion strategies accordingly. Resets of the infrastructure and scores will also be possible, but will result in overall point deduction.
