This PDF file was identified as malicious by multiple heuristics and a machine learning classifier, with ClamAV detecting it as Pdf.Phishing.Trojan. The presence of a "PDF_SEO_LINK_FARM" heuristic indicates the document likely contains numerous external links, with one prominent example being "https://trafftec.ru/strik?keyword=portfolio+management+tools+free". This suggests the document's primary purpose is to redirect users to potentially malicious or spam-related websites, fitting a phishing or link-farming attack pattern.

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://trafftec.ru/strik?keyword=portfolio+management+tools+free
