MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains heuristics indicating it is a malicious redirector, specifically designed to lure users with content related to 'quarter note beats per minute' and direct them to the URL https://trafffi.ru/aws?keyword=quarter+note+beats+per+minute. This URL is flagged as an SEO redirector, commonly used in phishing campaigns to obscure the final malicious destination. No scripts were extracted, but the PDF structure and embedded URI strongly suggest a phishing or malware delivery attempt.

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.
