MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF document flagged as malicious by ML classifiers and ClamAV. It contains an embedded URL, 'https://pelibifir.ru/aws?utm_term=whirlpool+cabrio+washer+will+not+power+on', which is likely used to redirect the user to a phishing or malware-hosting site. The document body, though heavily obfuscated, appears to reference the URL's subject matter, suggesting a lure.

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.
