T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains a heuristic indicating an embedded external URI, which points to a suspicious domain. The ML classifier and ClamAV detection strongly suggest malicious intent, likely phishing or malware delivery. The document body, though heavily obfuscated, appears to be a lure related to a Spanish worksheet, aiming to trick users into visiting the malicious URL.

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://zajinet.ru/strik?utm_term=possessive+pronouns+spanish+worksheet
