T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains multiple heuristics indicating it is a malicious redirector, specifically designed to lead users to phishing or malware distribution sites. The embedded URL 'https://traffine.ru/strik?utm_term=%25D9%2585%25D8%25B9%25D8%25AF%25D8%25A7%25D8%25AA+%25D8%25B7%25D9%258A%25D8%25B1%25D8%25A7%25D9%2586+%25D8%25A7%25D9%2584%25D9%2586%25D8%25AC%25D8%25A7%25D8%25A9' is flagged as a known malicious redirector. Additionally, the document contains a link farm of 28 external PDF links, many of which are hosted on platforms like strikinglycdn.com and weebly.com, suggesting an attempt to obscure the final malicious destination.

-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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.
-
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://traffine.ru/strik?utm_term=%25D9%2585%25D8%25B9%25D8%25AF%25D8%25A7%25D8%25AA+%25D8%25B7%25D9%258A%25D8%25B1%25D8%25A7%25D9%2586+%25D8%25A7%25D9%2584%25D9%2586%25D8%25AC%25D8%25A7%25D8%25A9 In PDF document text
