T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, many pointing to PDF files, suggesting a link farm or SEO poisoning tactic. One prominent URL, 'https://jacksth.ru/wix?keyword=orbot+proxy+con+tor+apk', indicates a lure related to 'orbot proxy con tor apk'. The ClamAV detection and ML classifier strongly suggest malicious intent, likely for phishing or malware distribution via these links.

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://jacksth.ru/wix?keyword=orbot+proxy+con+tor+apk
