这篇文章是对afl的简单使用，可大致分为黑盒测试和白盒测试两个部分。白盒测试从对目标程序的插桩编译开始，然后使用fuzzer对其模糊测试发现崩溃，最后对测试的代码覆盖率进行评估。黑盒测试则演示得较简略。参考：https://paper.seebug.org/841/#_1

接触这个词语已经有一年了，但还没有学习过更没有上手实践过，正好趁这个机会好好弄弄AFL。提起模糊测试，我们总会联想起这样或那样的专业术语——测试用例、代码覆盖率、执行路径等等，你可能和我一样一头雾水，这次我们就来看个明白

壳是最早出现的一种专用加密软件技术。一些软件会采取加壳保护的方式。壳附加在原始程序上，通过Windows加载器载入内存后，先于原始程序执行，以得到控制权，在执行的过程中对原始程序进行解密还原，然后把控制权还给原始程序，执行原来的代码。加上外壳后，原始程序在磁盘文件中一般是以加密后的形式存在的，只在执
