MITRE ATT&CK
T1203 Exploitation for Client Execution

The file is identified as malicious by ClamAV with the signature Doc.Dropper.Agent-7084142-0. The OLE document structure shows a significant amount of slack space, which is often used to hide malicious content. While no document body or scripts were extracted, the combination of the ClamAV detection and the OLE slack anomaly strongly suggests the file is a dropper designed to exploit a client-side vulnerability and download a secondary payload.

Heuristics 2

  • ClamAV: Doc.Dropper.Agent-7084142-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Agent-7084142-0
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 84,992 bytes but its declared streams total only 16,486 bytes — 68,506 bytes (81%) 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).
