shellcodeloader's Introduction

ShellcodeLoader

将shellcode用rsa加密并动态编译exe,自带几种反沙箱技术。

如果要用 .NET 2.0编译请手动编译,csc不支持某些代码

反沙箱

  • 判断父进程是否为Debugger

  • 判断时间是否加速

一般沙盘内的程序时间都会加速。

  • 判断进程是否有黑名单

判断是不是虚拟机,不过有几个vm进程是本机也会存在的,怕误报可以手动修改黑名单列表。

  • 判断MAC地址是否有黑名单

判断是不是虚拟机的mac地址,有几个地址只要本机有装虚拟机也会有,怕误报可以手动修改黑名单列表。

  • 判断系统盘是否大于50GB

一个正常PC的系统盘都会大于50GB。
