This PDF document was flagged by multiple heuristics as malicious, including a high-confidence ML classifier and ClamAV detection. The content and structure strongly indicate an advance-fee scam, aiming to trick users with promises of prizes or parcels. The embedded URL, https://midufefew.ru/wix?keyword=receipt+hog+apkpure, likely serves as a lure to a malicious site or further download. No scripts were extracted, but the PDF structure itself is leveraged for the malicious lure.

  • Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LURE
    Document 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_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.
