MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file was flagged by multiple heuristics as malicious, specifically for containing links to a known malicious redirector and a large number of external links, suggesting a link farm for SEO manipulation or malware distribution. The ML classifier also strongly indicated maliciousness. The primary attack pattern involves redirecting users to potentially harmful websites.

Heuristics 5
-
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://ttraff.com/pify?keyword=%25D0%25B8%25D1%2581%25D0%25BA%25D1%2583%25D1%2581%25D1%2581%25D1%2582%25D0%25B2%25D0%25B5%25D0%25BD%25D0%25BD%25D1%258B%25D0%25B9+%25D0%25B8%25D0%25BD%25D1%2582%25D0%25B5%25D0%25BB%25D0%25BB%25D0%25B5%25D0%25BA%25D1%2582+%25D1%2581%25D0%25BE%25D0%25B2%25D1%2580%25D0%25B5%25D0%25BC%25D0%25B5%25D0%25BD%25D0%25BD%25D1%258B%25D0%25B9+%25D0%25BF%25D0%25BE%25D0%25B4%25D1%2585%25D0%25BE%25D0%25B4+pdf In PDF document text
