MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file exhibits significant slack space within its OLE structure, a common characteristic of packed or obfuscated malicious documents. ClamAV identifies it as 'Img.Dropper.PhishingLure', strongly suggesting a phishing or scam-related lure. The embedded image data, though truncated, likely serves as the visual component of this lure. No scripts were extracted, and the document body was unreadable.

Heuristics 3

  • ClamAV: Img.Dropper.PhishingLure-6443153-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Img.Dropper.PhishingLure-6443153-0
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 220,672 bytes but its declared streams total only 24,673 bytes — 195,999 bytes (89%) 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).
  • 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.
