MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a high-severity heuristic firing indicating it's a phishing lure using an SEO redirector to a suspicious URL. The ClamAV detection and ML classifier also flag it as malicious. The embedded URL points to a known malicious domain, likely intended to deliver a secondary payload or redirect to a phishing page.

  • 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.
