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

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://traffset.ru/aws?utm_term=million+dollar+habits+brian+tracy+pdf` is identified as a redirector for SEO-based phishing. ClamAV also detected this file as a phishing trojan. No scripts were extracted, but the overall pattern suggests a phishing attempt.

  • 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.
