T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a lure referencing 'The tattooist of Auschwitz summary chapter 1' and includes a high-risk heuristic for an SEO redirector link. This link, https://seumenha.ru/strik?utm_term=the+tattooist+of+auschwitz+summary+chapter+1, likely leads to a phishing page. ClamAV also detected this file as Pdf.Phishing.Trojan. The embedded content is heavily obfuscated and does not contain directly executable scripts, but the overall structure and heuristics strongly indicate a phishing attempt.

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://seumenha.ru/strik?utm_term=the+tattooist+of+auschwitz+summary+chapter+1 PDF link annotation
