T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, many of which are likely part of a link farm designed to manipulate search engine results. One prominent external URI points to a URL that mimics a search query for software, suggesting a phishing or SEO-based malware distribution tactic. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or trojan delivery.

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://irlanc.ru/wb?keyword=data%20flow%20diagram%20software%20free%20download%20windows%207
