T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that leads to a domain associated with malicious activity, as indicated by the ML classifier and ClamAV detection. The document body, though heavily obfuscated, suggests a lure related to a 'crossword puzzle maker'. The presence of embedded URLs and the overall malicious classification point towards 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://jacksth.ru/strik?utm_term=crossword+puzzle+maker+free+printable+no+download
