T1059.007 JavaScript
The PDF contains a link to a known malicious redirector infrastructure, identified by the 'PDF_MALICIOUS_REDIRECTOR_LINK' heuristic. The ML classifier also strongly indicated maliciousness. While no scripts were extracted, the presence of a malicious URL within the document body suggests an attempt to redirect the user to a phishing or malware distribution site.

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://traffmen.ru/aws?utm_term=antivirus+microsoft+security+essentials+windows+7 In PDF document text
