T1566.001 Spearphishing Attachment
The file is a PDF with a high ML classifier score and ClamAV detection, indicating malicious intent. It contains an embedded URI pointing to a URL, which is a common tactic for phishing or directing users to malicious sites. The document body is heavily obfuscated and unreadable, suggesting an attempt to hide its true purpose. No scripts were extracted, but the presence of an embedded URI is sufficient evidence for a phishing attack pattern.

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://feedproxy.google.com/~r/razvivatel/yapz/~3/0YvHz_IItD0/square?utm_term=strong+winged+birds+related+to+the+albatrosses
