The PDF file contains a heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it directs users to known malicious infrastructure. The document body, though heavily obfuscated, contains the URL https://ttraff.me/wix?keyword=giancoli+physics+6th+edition+chapter+4, which is also flagged as malicious. The presence of a SE_CALLBACK_LURE heuristic suggests a phishing or scam pretext, likely aiming to trick users into clicking the malicious link under the guise of accessing educational material.

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.
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
  • 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.
    URL https://ttraff.me/wix?keyword=giancoli+physics+6th+edition+chapter+4
