IDF实验室 CTF训练营

CySCA CTF 官方write up Web篇. SCTF - - RE50静态分析. CTF夺旗赛通常有两种形式，解题模式 Jeopardy 和攻防模式 Attack-Defense。在解题模式的比赛中，主办方会提供一系列不同类型的赛题，比如上线一个有漏洞的服务、提供一段网络流量、给出一个加密后的数据或经过隐写后的文件等，他们将 flag 隐藏在这些赛题中，选手们通过比拼解题来一决高下在攻防模式比赛中，主办方会事先编写一系列有漏洞的服务，并将它们安装在每个参赛队伍都相同的环境中，参赛队伍一方面需要修补自己服务的漏洞，同时也需要去攻击对手们的服务、拿到对手环境中的 flag 来得分，攻防模式的竞赛往往比解题模式的竞赛更接近真实环境，比赛过程也更加激烈。 MISC(miscellaneous)类型的题目比较杂乱，可能要分析数据，可能需要百度一下，还可能需要脑筋急转弯 PPC(Professionally ProgramCoder)会考察一些编程类的题目是CRYPTO是密码学，考察各种加解密技术，当然这和软件加密解密的REVERSE技术是两码事。 IDF实验室 www.idf.cn.
