T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ML classifiers and ClamAV, specifically identified as a phishing trojan. It contains an embedded URI pointing to 'trafffi.ru', which is likely part of a phishing lure. The document body, though heavily obfuscated, suggests a pretext related to a 'World master chefs association'. No scripts were extracted, but the presence of external URIs and the malware detection strongly indicate a phishing or malware distribution attempt.

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/strik?utm_term=world+master+chefs+association+for+cantonese+cuisine PDF link annotation
