新增加的两位是CrowdStrike Falcon(以前觉得很强,感觉现在变弱了)和TrendMicro-HouseCall

根据VT说
Code insights
The sample demonstrates the 'MirrorExec' technique, which is used to bypass Data Execution Prevention (DEP) by double-mapping a shared memory section. The binary creates a file mapping backed by the system paging file (using CreateFileMappingA with INVALID_HANDLE_VALUE) and maps it twice: once with write permissions (FILE_MAP_WRITE) and once with execute permissions (FILE_MAP_EXECUTE). It then writes shellcode/assembly instructions (including a basic string length calculator) into the writable view and executes them through the executable view. While this dual-mapping evasion technique is highly suspicious and typical of advanced shellcode loaders, the specific sample contains verbose console logging and debug strings ('MirrorExec DEP Bypass', 'Create a bidirectional mapping') indicating it is an educational proof-of-concept (PoC) rather than a malicious payload.

样本演示了“镜像执行”(MirrorExec)技术,该技术通过双重映射共享内存段来绕过数据执行保护(DEP)。该二进制文件创建了一个基于系统分页文件的文件映射(使用 INVALID_HANDLE_VALUE 调用 CreateFileMappingA),并将其映射两次:一次具有写入权限(FILE_MAP_WRITE),一次具有执行权限(FILE_MAP_EXECUTE)。然后,它将 Shellcode/汇编指令(包括一个基础的字符串长度计算器)写入可写视图,并通过可执行视图执行它们。虽然这种双重映射规避技术高度可疑,且是高级 Shellcode 加载器的典型特征,但该特定样本包含了详细的控制台日志输出和调试字符串(如 'MirrorExec DEP Bypass'、'Create a bidirectional mapping'),表明它只是一个教育性的概念验证(PoC)程序,而非恶意攻击载荷。
