Zprotect1.4-1.6patchKEY脱壳-创新互联
对于ZProtect 1.4.x版本的系列软件，只要有其一个可用的机器码和key就可实现完美脱壳。
对于ZProtect 目前版本（ZP1.60）加壳的所有软件，只要有其一个可用的机器码和key就可实现完美脱壳。
假设已有一个可用的机器码和KEY：
机器码：AAAA-BBBB-CCCC-DDDD
序列号：B131FA844E0E9A7F32810DD67B9C4DC086EB
脚本流程：
1，寻找OEP断点。这个原理很简单，所谓的ESP平衡定律就是了。
2，对机器码进行补丁。zprotect用DeviceIoControl函数获取机器码相关，只要对该函数设置断点即可。当提示需输入机器号的前8位时，本例中，输入AAAABBBB，后8位即为CCCCDDDD。
3，修复IAT。本版本中IAT的起始和结束部分仍然需要手动填入。
4，用loadpe和IMR修复即可。
