MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains a critical heuristic firing indicating a malicious redirector link. The document body and heuristics suggest an advance-fee scam lure, aiming to trick the user into clicking the embedded URL. The primary malicious IOC is the redirector URL, which is likely the first step in a phishing or scam campaign.

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.
