T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains an embedded URI pointing to a suspicious domain, trafffi.ru. ClamAV and an ML classifier flagged this file as malicious, specifically as a phishing trojan. The document body, though heavily obfuscated, suggests it is masquerading as a template, a common lure for phishing attacks. The presence of external URIs indicates an attempt to redirect the user to a potentially malicious site.

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://trafffi.ru/aws?utm_term=microsoft+word+weekly+calendar+template+2019 PDF link annotation
