T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
T1059.007 JavaScript
The PDF file is flagged as malicious by ClamAV and an ML classifier, with heuristics indicating it's a phishing lure for a browser extension. The embedded URL `https://traffset.ru/aws?utm_term=flipshope+chrome+extension+app` supports this social engineering pretext. While no scripts were directly extracted, the PDF structure and the nature of the lure suggest potential exploitation for client execution, possibly involving embedded JavaScript.

Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation

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://traffset.ru/aws?utm_term=flipshope+chrome+extension+app
