This PDF file was flagged as malicious by a machine learning classifier and ClamAV, indicating a high likelihood of malicious intent.

The document body, though heavily obfuscated, suggests a lure related to 'famous biologists and their contributions', a common tactic for phishing or malware distribution.

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://trafffi.ru/aws?utm_term=famous+biologists+and+their+contributions+pdf PDF link annotation
