  • 导入地址表 (IAT) 规避

  • 加密有效负载(XOR 和 AES)

  • 随机生成的密钥

  • x90使用 NOPS ( )自动填充有效负载(如有必要)

  • 有效负载的逐字节内存解密

  • XOR 加密字符串

  • PPID欺骗

  • 阻止非 Microsoft 签名的 DLL

  • (可选)克隆PE图标和属性

  • (可选)使用欺骗性证书进行代码签名

Shellcode 执行技术

  1. Early-bird APC Queue (需要牺牲过程)

  2. 线程劫持(需要牺牲进程)

  3. KernelCallbackTable (需要具有 GUI 的牺牲进程)

  4. 截面视图映射

  5. 线程暂停

  6. LineDDA回调

  7. EnumSystemGeoID 回调

  8. 光纤本地存储 (FLS) 回调

  9. 设置定时器

  10. 剪贴板
