T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was flagged as malicious by ML classifiers and ClamAV, indicating a phishing or trojan payload. It contains a large number of external links, with one pointing to 'https://traffine.ru/strik?utm_term=bed+bath+and+beyond+bed+skirt+pins', suggesting a link farm or phishing lure. The document body, though heavily obfuscated, appears to contain search-related terms, reinforcing the lure. No scripts were extracted, but the PDF structure and numerous external links are indicative of malicious intent.

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://traffine.ru/strik?utm_term=bed+bath+and+beyond+bed+skirt+pins
