T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a malicious redirector link pointing to 'https://cctraff.ru/123?keyword=knights+of+columbus+fish+fry+2018'. This is further supported by a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK and a high ML score. The document body, though heavily obfuscated, also contains the same URL, indicating its primary purpose is to lure the user to this malicious destination.

Heuristics 3
-
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.
-
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://cctraff.ru/123?keyword=knights+of+columbus+fish+fry+2018 In PDF document text
