T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF containing obfuscated content and a heuristic firing for an external URI. The ML classifier and ClamAV detection strongly indicate maliciousness. The embedded URL points to a suspicious domain, likely used for phishing or malware distribution. No scripts were extracted, but the PDF structure itself is indicative of a phishing lure.

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://krisoc.ru/pbw?utm_term=92+in+periodic+table
