MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file exhibits a significant amount of slack space, which is a common technique used to hide malicious content within otherwise legitimate files. ClamAV detection as 'Img.Dropper.PhishingLure' strongly indicates a phishing or deceptive purpose. 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 252,416 bytes but its declared streams total only 24,693 bytes — 227,723 bytes (90%) 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.
