MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains a lure impersonating a 'Netflix error 10000' to trick users into clicking a malicious URL. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms this, pointing to 'https://ttraff.cc/pify?keyword=netflix++error+10000'. Additionally, the PDF_SEO_LINK_FARM heuristic indicates a large number of embedded links, with 'https://cdn.shopify.com/s/files/1/0434/1052/2279/files/nutrition_an_applied_approach_5th_edition_free.pdf' being one of them, suggesting a broad distribution or SEO-poisoning tactic.

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.
