"description": "ByteCTF由字节跳动安全中心发起，大赛通过以赛代练的方式选拔优秀的高校人才。赛题由字节跳动攻防专家、密码安全专家及安全工程师精心设计，深度结合字节跳动业务场景，真实考察选手的工程能力和思考深度，比赛中能感知到业务场景和真实攻防结合的沉浸式体验。\n\n**温馨提示：参赛单元为1-5人的队伍（单人可参加比赛，但也需组建1人的队伍，未完善个人及团队信息无法答题）**",

"rule": "# Flag格式\n\nByteCTF{xxxxxxxxxxxxxxxxxxxxx} \n\n提交时包含格式。\n\n# 积分规则\n\n## 得分与排名\n\n每道题会标注题目说明与赛题得分，当队伍提交正确的“Flag”后，该题积分自动计入队伍总积分，排行榜随时更新。\n\n题目采用动态积分制，每道题目初始积分为1000，题目积分会随着解出队伍的增加而减少，最终达到一个平衡分值（解出该题的队伍得分一致）。\n\n最终排名根据每个队伍的总分确定，在多个队伍得分相同的情况下，越早达到这一分值的排名越高。\n\n# 比赛红线\n\n1. 禁止不同参赛队伍合作或共享解题思路，一经发现，取消参赛资格。\n2. 禁止对答题平台发起攻击获得答案，一经发现，取消参赛资格。\n3. 比赛期间一个同学只能参加一个队伍并不能退队。\n4. 前 25 名需提交赛题解题报告。\n\n# 奖励规则\n\n## TOP 5 团队奖励\n\nByteCTF冠军 1队：30000元\n\nByteCTF亚军 1队：20000元\n\nByteCTF第3-5名：8000元\n\n## 优胜团队奖励\n\nByteCTF前20支战队，每位队员奖励周边大礼包一份。\n\n## 校招实习绿色通道\n\nTOP 10 团队同学可享受校招实习绿色通道，直通复试。\n\n# 赛事答疑\n\n请添加QQ：3472473732，备注团队名+真实姓名。",
