T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file was detected as a malicious PDF by ML classifiers and ClamAV. It contains multiple embedded URLs, one of which is flagged as benign, but others are unknown and potentially malicious. The document body is heavily obfuscated, preventing a clear understanding of its specific lure, but the presence of numerous PDF_URI and EMBEDDED_URL heuristics suggests a phishing or redirection attempt. No scripts were extracted from this sample.

-
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://www.guninetwork.org/system/files/webform/heirri_proposals/nuxikovevevugodir.pdf In PDF document text
