MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to public relations management, directing the user to a suspicious URL. The ML classifier also flagged the PDF as malicious. While no scripts were explicitly extracted, the presence of an external URI and the ML classification suggest malicious intent, likely to download a second-stage payload.

Heuristics 3

  • Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINK
    PDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.
  • External URI info PDF_URI

  • Embedded URL info EMBEDDED_URL
