T1059.007 JavaScript
T1203 Exploitation for Client Execution
This PDF file was identified as malicious by multiple heuristics and a machine learning classifier, with ClamAV detecting it as a phishing trojan. The file contains a large number of external links, suggesting it functions as a link farm or SEO spam document. The primary URL, https://ponafet.ru/strik, is likely used to distribute further malicious content or lead users to phishing sites. No scripts were extracted, but the presence of numerous external links and the overall structure strongly indicate a malicious intent to redirect users.

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://ponafet.ru/strik?utm_term=after+the+quake+monterey
