The sample was flagged by a machine learning classifier and ClamAV as malicious, specifically as a phishing trojan. Heuristics indicate social engineering attempts to bypass security by instructing the user to disable antivirus and execute commands, consistent with ClickFix attacks. An external URI was also identified, suggesting a potential download or redirection point.

-
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
-
Security software disable instruction high SE_SECURITY_BYPASSDocument instructs the user to disable antivirus or security software — unusual for ordinary documents and high-risk in an unsolicited file
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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/123?utm_term=adobe+creative+cloud+direct++helpx PDF link annotation
