T1566.001 Spearphishing Attachment
The file was detected as malicious by ML classifiers and ClamAV, specifically identified as a phishing trojan. It contains an embedded URL that, while currently flagged as benign, is a common indicator of phishing or malware distribution schemes. The PDF structure itself is also noted as having duplicate objects, which can be used to obfuscate malicious content.

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/sq/ugae/~3/um1bUVUAM38/square?utm_term=i+want+to+see+you+in+spanish
