T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by a machine learning classifier and ClamAV, specifically flagged as a phishing trojan. It contains an embedded URL that impersonates a Windows update notification, likely intended to trick the user into clicking it. No scripts were extracted, but the presence of the malicious URL and the phishing lure strongly indicate a social engineering attack.

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://traffnew.ru/aws?utm_term=ultimi+aggiornamenti+windows+xp PDF link annotation
