T1566.001 Spearphishing Attachment
The sample is a PDF file flagged by ClamAV as a phishing trojan and by an ML classifier as malicious. It contains an embedded URI pointing to the suspicious domain 'inwebjor.ru'. While no scripts were explicitly extracted, PDFs can embed JavaScript for malicious actions, and the presence of a malicious URL suggests an attempt to redirect the user to a harmful site, likely as part of a phishing or malware delivery scheme.

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://inwebjor.ru/square?utm_term=american+stafford+puppies
