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://nipisod.ru/strik?utm_term=how+to+assemble+mainstays+bathroom+space+saver` is identified as a redirector for free-download phishing. ClamAV also detected this file as a phishing trojan. No scripts were extracted, but the overall pattern suggests a phishing attempt disguised as helpful content.

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://nipisod.ru/strik?utm_term=how+to+assemble+mainstays+bathroom+space+saver PDF link annotation
