The file is a PDF document flagged by multiple heuristics as malicious, including a high-confidence ML classifier and ClamAV detection. The 'SE_INVOICE_LURE' heuristic indicates the document's content is designed to trick the user. The embedded URL `https://bologen.ru/award?keyword=turkey+bird+farming+pdf+bangla` is the primary indicator of a malicious redirection or download attempt, aligning with spearphishing tactics.

  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The 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_URL
    One 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.
