MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with the signature Win.Trojan.Tristate-2. The document body explicitly warns of a macro virus infection, indicating a social engineering tactic to prompt the user to enable macros. The large slack space in the OLE structure is also anomalous, though its specific role is unclear without further analysis.

Heuristics 2

  • ClamAV: Win.Trojan.Tristate-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Tristate-2
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 52,736 bytes but its declared streams total only 18,572 bytes — 34,164 bytes (65%) 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).
