T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF that contains embedded URLs, one of which points to a suspicious domain ('golowaki.ru'). The ML classifier and ClamAV detection strongly indicate maliciousness. The document body, though heavily obfuscated, suggests a lure related to a 'noun clauses quiz pdf' or an 'award', which is a common phishing tactic. The presence of embedded URLs and the nature of the detection suggest this file is likely part of a phishing campaign or a malware distribution effort.

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://golowaki.ru/award?keyword=noun+clauses+quiz+pdf
