Description
|
This challenge was part of the finals During finals, scoring happens per-round based on attack (steal flags from others) and defense (patch the service to prevent others from pwning you) points. Patching is not currently simulated on the archive, but keep in mind that most services only allowed a limited amount of bytes to be changed from the original binary. Scoring rules for 2019 2020 2021. | |

King of the Hill points are also awarded per-round, with only the top-ranking teams getting points. Teams were informed of game events, with redacted info on the last day. In 2019 players could see traffic pcaps only after some time, in 2020 and 2021 they had the choice the stealth their traffic or not (for half the points). | |
