MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains an embedded URI pointing to a suspicious external website, identified by the 'ML_NYX_PDF_MALICIOUS' heuristic. The document body, though heavily obfuscated, appears to contain text related to 'Printed canvas cross stitch kits', likely a lure. No scripts were extracted, but the presence of an external link suggests an attempt to redirect the user to a malicious site, potentially for phishing or malware delivery.

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.
