T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by a ClamAV detection and an ML classifier, indicating a high likelihood of malicious intent. It contains an embedded URI pointing to 'https://trafffi.ru/123?utm_term=perfectly+competitive+market+graph+surplus', which is a strong indicator of a phishing or malware distribution attempt. The document body is heavily obfuscated, but the presence of the external URI and the ClamAV detection strongly suggest a malicious purpose, likely related to phishing or delivering a second-stage payload.

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/123?utm_term=perfectly+competitive+market+graph+surplus PDF link annotation
