T1059.007 JavaScript
The PDF document contains multiple embedded URLs, with a high-confidence heuristic identifying one as an SEO redirector for a free-download phishing lure. The primary malicious URL, https://mezovuduw.ru/strik?utm_term=which+of+the+following+describes+an+empirical+probability+%2528i.s.+not+a+theoretical+one%2529, is likely intended to lead the user to a malicious site. No scripts were extracted, but the document structure and embedded links strongly suggest a phishing or malware distribution attempt.

Heuristics 5
-
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.
-
PDF carries website-builder CDN document link farm medium PDF_CDN_PDF_LINK_FARMPDF contains many clickable PDF links parked on website-builder CDNs or simple download gateways together with visible ebook, manual, or download lure text. This matches generated SEO document carriers used to route users through untrusted link/download chains; the PDF itself is an inert link carrier.
-
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://mezovuduw.ru/strik?utm_term=which+of+the+following+describes+an+empirical+probability+%2528i.s.+not+a+theoretical+one%2529 PDF link annotation
