T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many of which point to potentially malicious or scam-related content, as indicated by the 'PDF_SEO_LINK_FARM' heuristic. The primary URL, 'https://jumiwimov.ru/strik?utm_term=baby+boy+names+book+characters', suggests a lure related to baby names, likely for phishing or a scam. While no scripts were explicitly extracted, the PDF structure and numerous external links strongly suggest malicious intent, possibly involving JavaScript execution or redirection to malicious sites.

External URI info PDF_URIPDF contains an external URL action

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://jumiwimov.ru/strik?utm_term=baby+boy+names+book+characters
