MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains heuristics indicating it is a phishing lure, specifically using an image to redirect users to a malicious URL. The embedded URL, 'https://trafficel.ru/aws?utm_term=c%25C3%25A1ch+chuy%25E1%25BB%2583n+%25E1%25BA%25A3nh+t%25E1%25BB%25AB+pdf+sang+jpg', is identified as a redirector for free-download phishing. Although no scripts were explicitly extracted, the PDF structure and the presence of external URIs suggest an attempt to download or redirect to malicious content.

  • 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.
