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

The PDF file contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.cc/wix?keyword=le+loup+et+l+agneau+r%25C3%25A9sum%25C3%25A9'. Additionally, it exhibits characteristics of a PDF link farm, embedding a large number of external links, with 'https://cdn.shopify.com/s/files/1/0431/7341/3032/files/kedasobavesifewewekine.pdf' being one of the first identified. The document body, though partially corrupted, includes the title 'Le loup et l agneau résumé' and the malicious URL, suggesting a lure to a malicious site.

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.
