MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The ML classifier strongly indicated maliciousness in this PDF. The document contains multiple embedded URLs, with the primary one being http://jewels-hair-studio.com/uploads/1/3/0/2/130291492/130291492.html#latin+bass+book+cd. This suggests a social engineering attack where the user is prompted to click a link, likely leading to a phishing page or a download of further malicious content. No scripts were extracted, limiting the analysis of the exact payload.

Heuristics 3

  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
