T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of embedded links, many of which point to a redirector service. The primary malicious URL identified is https://ttraff.cc/wix?keyword=... which is designed to lead users to further malicious content. The presence of a link farm and a malicious redirector strongly suggests a phishing or malware distribution attempt.

Heuristics 4
-
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.
-
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.cc/wix?keyword=%25D1%2582%25D0%25B5%25D0%25BE%25D1%2580%25D0%25B5%25D1%2582%25D0%25B8%25D1%2587%25D0%25B5%25D1%2581%25D0%25BA%25D0%25B0%25D1%258F+%25D0%25BC%25D0%25B5%25D1%2585%25D0%25B0%25D0%25BD%25D0%25B8%25D0%25BA%25D0%25B0+%25D0%25BC%25D0%25B5%25D1%2589%25D0%25B5%25D1%2580%25D1%2581%25D0%25BA%25D0%25B8%25D0%25B9+%25D0%25B7%25D0%25B0%25D0%25B4
