T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document that contains embedded URLs, one of which is flagged as unknown reputation. The ML classifier and ClamAV detection strongly indicate maliciousness. The document body, though heavily obfuscated, suggests a lure related to a movie review, which is a common tactic for phishing or malware delivery. No scripts were extracted, but the presence of malicious PDF indicators points towards an attempt to exploit vulnerabilities or redirect users to malicious sites.

-
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 http://cicatsalud.com/html/sites/default/files/webform/jowodudarazobipadumalo.pdf In PDF document text
