T1059.007 JavaScript
The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure, specifically 'https://gettraff.ru/123?utm_term=tejido+conjuntivo+laxo+donde+se+encuentra'. ClamAV also detected it as 'Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0'. The ML classifier strongly flagged this PDF as malicious. The embedded document body text appears to be corrupted or obfuscated, but the presence of a malicious redirector URL is a strong indicator of a phishing or malware distribution attempt.

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://gettraff.ru/123?utm_term=tejido+conjuntivo+laxo+donde+se+encuentra
