MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is an OLE document with a significant amount of slack space, indicating potential obfuscation or embedded malicious content. ClamAV detected it as 'Img.Dropper.PhishingLure', suggesting it's designed to drop or present a phishing lure, possibly disguised as an image. The embedded URL, though benign, is present within the document structure.

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 149,504 bytes but its declared streams total only 24,677 bytes — 124,827 bytes (83%) 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.
