A letter from CyberGame developers

9. March 2026 Dear players, last week we informed you about multiple violations of game rules which affect fair play. After careful deliberation, we believe we have developed a plan that promotes fairness and enables CyberGame to continue. 1. the following challenges will be redesigned. The existing solves will be nullified, and players will need to solve them again. The same principle will apply, so this should be easy to do for anyone who managed to solve them the first time. During the process of solving, please do NOT upload artifacts to any service.

• RSA - French technology

2. the following challenges will be kept on the platform, but the final scoreboard will be adjusted after the CyberGame ends: time of solve of this challenge will be ignored (will not influence ranking if the players share the same score) to make up for the fact that some players already unlocked these challenges when we took down their prerequisity. What does not change? The challenge will still be scored and players should try to solve it, if they want to reach the highest ranks.

• RSA - Prime Classes
• RSA - Hellish RSA
• RSA - Exponent works
• RSA - French technology
• JailPS - safeps
• JailPS - safeps2

3. based on review of the logs and other evidence, we don't believe players could have benefited from the other challenges where the solution may have been posted online. Since the content is no longer available, we are keeping theme as-is. PLEASE DO NOT share artifacts or full solutions online, including but not limited to:

• web sites,
• video platforms,
• file sharing platforms and software repositories,
• specialized online services for cryptographers.

Thank you. If you have any thoughts or questions, please contact us on Discord. The CyberGame Developers.
