T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document was flagged by a critical heuristic for linking to known malicious redirector infrastructure, specifically the URL https://ttraff.ru/wix?keyword=pathfinder+pawns+npc+codex+box+pdf. Additionally, another critical heuristic identified it as a PDF link farm containing numerous external links, with the first being https://static.usrfiles.com/ugd/b8c837_3a08abdde3d64b1598a162903453a622.pdf. The ML classifier also strongly indicated maliciousness. These findings suggest the primary purpose of this PDF is to lure users to malicious sites.

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.ru/wix?keyword=pathfinder+pawns+npc+codex+box+pdf
