MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains heuristics indicating it's a phishing lure, specifically using an image to redirect users to a malicious URL. The embedded URL and the ClamAV detection further support its malicious nature. While no scripts were explicitly extracted, the PDF structure and the nature of the heuristics suggest it is designed to trick users into downloading further malicious content.

  • 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.
