MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file was detected as malicious by ClamAV and an ML classifier, with heuristics indicating it uses an image lure linking to an SEO redirector. The embedded URL points to 'bologen.ru', suggesting a phishing or malware distribution attempt. Although no scripts were explicitly extracted, the PDF structure and heuristics strongly suggest an attempt to trick users into clicking a malicious link, likely for initial access via spearphishing.

  • 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.
