T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/123?utm_term=pitch+perfect+script'. ML classification also strongly indicates maliciousness. While no scripts were explicitly extracted, the nature of the redirector suggests an attempt to lure the user to a malicious site, consistent with phishing or malware delivery.

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?utm_term=pitch+perfect+script In PDF document text
