T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a high-confidence heuristic indicating it's a phishing lure, specifically using an image link to an SEO redirector. The embedded URL 'https://bologen.ru/award?keyword=classification+of+antiulcer+drugs+pdf' is the primary indicator of this malicious intent. While no scripts were explicitly extracted, the PDF structure and the nature of the URL suggest a phishing attack designed to lead the user to a malicious site.

Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF 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.

External URI info PDF_URIPDF contains an external URL action

Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.

Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://bologen.ru/award?keyword=classification+of+antiulcer+drugs+pdf PDF link annotation
