MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, a common tactic for phishing. It contains a single embedded URI pointing to 'https://cempar.cl/wp-load/r5678.php#&page=_adbe3&pcnt=3'. The ML classifier also flagged this PDF as malicious. The combination of these factors strongly suggests the PDF is intended to trick the user into clicking the link, which likely leads to the download or execution of a malicious payload.

Heuristics 4

  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 239 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
