T1203 Exploitation for Client Execution
This PDF file was flagged as malicious by a machine learning classifier and ClamAV, indicating a high likelihood of malicious intent. The file's content, though heavily obfuscated, appears to be a lure, possibly for phishing or to download further payloads, as suggested by the presence of multiple external URLs. No scripts were extracted from this sample, limiting the ability to determine the exact execution mechanism.

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://cdn-cms.f-static.net/uploads/4495691/normal_6032726ddc990.pdf
