T1059.007 JavaScript
This PDF file was detected as malicious by ClamAV and an ML classifier, indicating a phishing or malware distribution attempt. It contains a mass of external links, with one pointing to 'trafffi.ru', suggesting a link farm or redirection to a malicious site. The document body, though heavily obfuscated, appears to contain keywords related to product listings, likely a lure to encourage clicks on the embedded malicious links.

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?keyword=air+fryer+copper+crisper+tray
