T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file is identified as malicious by multiple heuristics and a machine learning classifier. It contains a large number of external links, many pointing to other PDFs, suggesting a link farm designed to attract traffic or distribute malware. The primary URL, 'https://infrive.ru/pbw?utm_term=corel+draw+x5+full+version+with+keygen+free+download', indicates a lure related to software downloads, likely a phishing or scam attempt. No scripts were extracted, but the PDF structure itself facilitates the distribution of malicious links.

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://infrive.ru/pbw?utm_term=corel+draw+x5+full+version+with+keygen+free+download
