T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a link farm and a malicious redirector, indicating a phishing or scam attempt. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly suggests the document is designed to trick users into believing they are involved in a lottery or prize claim, requiring them to click a link for delivery confirmation. The primary malicious URL identified is 'https://ttraff.com/pify?keyword=b.+o.+c+born+sinner+music', which likely leads to further malicious content or phishing pages.

Heuristics 4

  • 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.
  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
