T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a link to a known malicious redirector, indicating a phishing attempt. The document body, though heavily obfuscated, suggests a lure related to retirement benefits ('kalkulator zus emerytura'). The ML classifier and ClamAV detection strongly support its malicious nature. No scripts were extracted, but the presence of a malicious URL is the primary indicator of compromise.

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=kalkulator+zus+emerytura
