T1204.002 Malicious Link
The PDF document exhibits characteristics of an advance-fee scam, including language related to lotteries, prizes, and parcel delivery. It contains a significant number of external links, with one pointing to 'https://zajinet.ru/strik?utm_term=android+app+development+cost' and another to 'https://detawokigar.weebly.com/uploads/1/3/1/4/131453745/bofurasubebemafixe.pdf', suggesting a link farm or redirection mechanism. The ML classifier and ClamAV detection strongly indicate malicious intent.

Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LUREDocument contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
-
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://zajinet.ru/strik?utm_term=android+app+development+cost
