The sample is a PDF document flagged by ClamAV as a phishing trojan. Heuristics indicate the presence of an external URI and urgency-related language, suggesting a phishing lure. The ML classifier also strongly indicated maliciousness. The embedded URL, https://trafficel.ru/strik?utm_term=gcc+bookstore+contact, is the primary indicator of a malicious destination.

Urgency / deadline lure low SE_URGENCY_LUREDocument contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
-
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://trafficel.ru/strik?utm_term=gcc+bookstore+contact PDF link annotation
