MITRE ATT&CK
T1059.001 PowerShell

The file is an OLE document with significant slack space, a common technique for hiding malicious code. The 'SC_PEB_ACCESS' heuristic indicates potential process manipulation. While no specific scripts were extracted, the presence of embedded URLs and the overall structure suggest a malicious container likely used for delivering further payloads.

Heuristics 2

  • PEB access via FS segment (x86) high SC_PEB_ACCESS
    PEB access via FS segment (x86)
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 214,528 bytes but its declared streams total only 16,486 bytes — 198,042 bytes (92%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
