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

The PDF contains a large number of external links, many of which are dynamically generated and point to unrelated content, indicating a link farm or SEO poisoning tactic. The document body mentions 'Youcam camera for laptop', suggesting a lure to attract users to click on the embedded malicious URLs. No scripts were extracted, and the primary malicious activity appears to be directing users to potentially harmful websites.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
