The PDF contains a mass external link farm, with many links pointing to Shopify domains, likely to improve search engine ranking for the malicious redirector URL. The document body contains the topic "React native touchablehighlight" and the malicious URL https://ttraff.com/pify?keyword=react+native+touchablehighlight, indicating a lure to a phishing or scam site. The heuristic "SE_CLIPBOARD_COMMAND_LURE" suggests the document may also instruct the user to interact with command-line tools, further increasing the risk.

Heuristics 4

  • 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.
  • Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LURE
    Document tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context
  • 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.
