Malware Insights

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

The PDF file contains heuristics indicating it uses an image lure to redirect users to an SEO redirector, specifically for a 'free-download phishing' scheme. The primary URL identified, https://zajinet.ru/award?keyword=possessive+adjectives+exercises+elementary+pdf, is associated with this lure. Although no scripts were explicitly extracted, the PDF structure and embedded URI suggest an attempt to trick users into downloading further malicious content or visiting a phishing site.

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.
