T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The ML classifier and ClamAV both flagged this PDF as malicious, with high confidence. The PDF contains embedded URLs, one of which is a known benign feedproxy URL, but others point to potentially malicious domains. The document body is heavily obfuscated, preventing a clear understanding of its direct content, but the presence of embedded URLs and the malware detection strongly suggest a phishing or malware distribution 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/gafazibo.pdf In PDF document text
