The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/pify?keyword=play+store+installieren+apk'. This URL is presented within the document body, disguised as a prompt to install an Android application. This, combined with the 'SE_ADVANCE_FEE_SCAM_LURE' heuristic, indicates the document is designed to trick users into visiting a malicious site, likely for financial fraud. No scripts were extracted from this sample.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
  • 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.
