T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a high number of embedded links, many pointing to what appears to be a link farm hosted on Shopify, with a critical heuristic firing for a malicious redirector. The primary malicious URL identified is https://ttraff.cc/pify?keyword=django+html+template+if+statement. This suggests the document's purpose is to redirect users to malicious infrastructure, likely for phishing or malware delivery. No scripts were extracted, but the PDF structure and URL analysis strongly indicate malicious intent.

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.
  • 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.
  • 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.
