T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The sample was identified as malicious by a machine learning classifier and ClamAV, with a specific detection of Pdf.Phishing.Trojan. The presence of embedded URLs, although many are marked as benign, suggests an attempt to direct users to external resources. The PDF structure itself contains anomalies, such as duplicate object bodies, which can be indicative of malicious obfuscation techniques.

-
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/iXsW93xxTQA/square?utm_term=shout+out+meaning+in+snapchat
