metame

metame metame 是一个用于任意可执行文件的简单变形代码引擎。 来自维基百科： 变形代码是指在运行时，能在某种解释下输出自身代码的逻辑等价版本的代码。 这被计算机病毒用来规避杀毒软件的模式识别。 metame 的实现方式如下： 1. 打开给定的二进制文件并分析代码 2. 随机用逻辑等价且大小相同的指令替换指令 3. 复制并修补原始二进制文件以生成变异版本 目前支持以下架构： x86 32 bits x86 64 bits 此外，它支持多种文件格式，因为使用了 radare2 进行文件解析和代码分析。 变异前后的代码示例： 提示：此片段中已替换了两条指令。 这里还有一个关于如何将...
