T1566.001 Spearphishing Attachment
The PDF file was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Phishing.Trojan' and an ML classifier indicating high maliciousness. The presence of a large number of external links, identified as a 'PDF_SEO_LINK_FARM', suggests an attempt to direct users to potentially malicious websites. The document body contains garbled text, indicating it is not intended for direct user consumption but rather as a container for these links.

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://traffnew.ru/strik?utm_term=husqvarna+chainsaw+disassembly
