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

The PDF document contains an embedded URL that redirects to a suspicious domain, identified as a potential SEO redirector for phishing or malware distribution. The heuristic 'PDF_SEO_UTM_REDIRECTOR_LINK' strongly suggests this is an image lure for free downloads, a common phishing tactic. While no scripts were explicitly extracted, the PDF structure and embedded URLs indicate a malicious intent to redirect the user to a compromised or malicious site.

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.
