MITRE ATT&CK
T1059.001 PowerShell T1059.003 Windows Command Shell T1218.011 Signed Binary Proxy Execution: Rundll32

The sample exhibits high-confidence heuristic firings indicating the use of PEB access and API hash resolution, common techniques for obfuscating API calls. It also references WinExec and CreateProcess, suggesting an intent to execute further code. The presence of an embedded URL, although benign according to reputation, is noted. No scripts were extracted from this sample, limiting the ability to determine the exact payload or execution flow.

Heuristics 6

  • x86 GetPC stub (CALL $+5; POP EAX) high SC_GETPC_CALL
    x86 GetPC stub (CALL $+5; POP EAX)
  • PEB access via FS segment (x86) high SC_PEB_ACCESS
    PEB access via FS segment (x86)
  • PEB API-hash resolver high SC_API_HASH_RESOLVER
    PEB access followed by ROR13-style API hashing, a common position-independent shellcode import resolver
  • Reference to WinExec API high SC_STR_WINEXEC
    Reference to WinExec API
  • Reference to CreateProcess API high SC_STR_CREATEPROCESS
    Reference to CreateProcess API
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
