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

The PDF file contains a high-severity heuristic indicating it is an SEO redirector link for a free-download phishing lure. The embedded URL 'https://traffnew.ru/123?utm_term=monster+park+mod+apk' is the primary indicator of this malicious activity. While no scripts were explicitly extracted, the PDF structure and the nature of the URL suggest an attempt to redirect the user to a malicious site, likely for malware distribution or phishing.

  • 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.
