T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a heuristic firing for a link farm, directing users to a suspicious URL (https://nipisod.ru/strik?utm_term=what+are+the+8+characteristic+of+life). ClamAV detection and an ML classifier also flagged this PDF as malicious, specifically as a phishing trojan. The document body, though truncated, suggests a lure related to 'characteristics of life', which is likely a pretext to drive traffic to the malicious site.

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://nipisod.ru/strik?utm_term=what+are+the+8+characteristic+of+life
