This PDF file was identified as malicious by ClamAV and an ML classifier, exhibiting characteristics of a social engineering attack. The document contains a large number of external links, with one prominent URL pointing to a potentially malicious domain, suggesting it's part of a link farm or phishing campaign. The 'SE_CLICKFIX' heuristic indicates the document likely attempts to trick the user into executing a command, possibly to download and run a second-stage payload.

ClickFix social engineering attack high SE_CLICKFIXDocument instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
-
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://xezojetit.ru/123?utm_term=can%2527+t+be+erased+free
