MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains an embedded URI that directs users to a website disguised as interview questions. This is a common lure for phishing or malware distribution. The ML classifier and ClamAV detection strongly indicate malicious intent, likely to lead the user to download a secondary payload or engage in credential harvesting.

External URI info PDF_URI

PDF contains an external URL action
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL

The 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_URL

One 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.
