This PDF was detected as malicious by ML classifiers and ClamAV, indicating a phishing or trojan payload. It contains an external URI pointing to 'jacksth.ru' which is likely a lure to download a malicious file. The document body, though heavily obfuscated, appears to be a search result for a technical book, suggesting a social engineering tactic to entice users to click the link and download a further payload.

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://jacksth.ru/wix?keyword=operating+system+concepts+9th+edition+pdf
