T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file was identified as malicious by a machine learning classifier and ClamAV, specifically flagged as Pdf.Phishing.Trojan. The embedded URL, 'https://trafffi.ru/123?utm_term=nova+lab+answer+key', is likely a phishing lure. Although no scripts were explicitly extracted, the PDF structure and the presence of an external URI suggest an attempt to redirect the user to a malicious site, aligning with spearphishing tactics.

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.
