MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a high-severity heuristic indicating it's a lure for free downloads, directing users to an external URL. This URL, 'https://jottigo.ru/award?keyword=dyson+vacuum+dc44+animal+parts', is likely part of a phishing or malware distribution scheme. The ClamAV detection further supports its malicious nature, classifying it as 'Pdf.Phishing.Trojan'. No scripts were extracted, but the embedded URI and redirector strongly suggest a phishing attack.

  • 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.
