        <p>近来做了许多ctf的RE题，用IDA分析确实方便，f5更是神器。但发现有些题目为了anti-f5,而对程序代码进行混淆，这样f5就无法直接反汇编回来，加大了逆向的难度。混淆有多种方式，例如加密部分代码，然后在程序运行后进行自解密。我们可以借助IDA的脚本idapython来模拟程序运行时的自解密，从而更好更方便的逆向分析。

        <p>这两天参加了RuCTFe比赛，是由俄罗斯Hackerdom组织面向全球参赛队伍的在线攻防赛。第一次接触攻防模式（Attack-Defense）的，抱着学习心态来体验下。之前只参加国内的ctf，初赛都是解题模式，实力不济，没进过决赛，对攻防模式确实陌生。虽然最后没有得分，但也是一次很好的经历体验，面对那么多的web框架，就知道自己的不足; 见识到新东西，开阔视野。</p>
