MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF contains numerous embedded links, with a critical heuristic identifying a malicious redirector at 'https://ttraff.cc/pify?keyword=n%25C3%25A9ologisme+exemple+pdf'. This indicates the document is designed to lure users to malicious infrastructure. The presence of a large number of external PDF links suggests a link farm or SEO poisoning tactic to increase visibility. No scripts were extracted, but the PDF structure and embedded links strongly suggest a phishing or scam delivery mechanism.

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.
