T1566.001 Spearphishing Attachment
The file is a PDF document that contains an embedded URL pointing to a suspicious domain, identified by ClamAV and ML classifiers as malicious. The document body, though partially corrupted, suggests a lure related to a 'free pdf download', likely intended to trick users into clicking the malicious link. The primary IOC is the external URI used for the malicious download.

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/strik?utm_term=french+wine+for+a+flat+belly+free+pdf+download
