T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a mass external link farm, with one critical link pointing to a known malicious redirector at 'https://ttraff.cc/pify?keyword=el+poder+curativo+de+la+cabala+pdf+gratis'. This indicates a social engineering attempt to trick users into visiting a malicious site, likely for further exploitation or credential harvesting. No scripts were extracted, but the PDF structure and embedded URLs strongly suggest a phishing or redirection attack.

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.
