MITRE ATT&CK
T1566.002 Spearphishing Attachment T1200 Hardware Add-Override

The PDF file was identified as malicious due to a high number of embedded links, many of which lead to redirector infrastructure. The document body contains the text 'Bruce leroy quotes' and several URLs, including a primary redirector at 'https://ttraff.club/wix?keyword=bruce+leroy+quotes' and a secondary link farm URL 'http://jiweb.icater2youtravel.com/uploads/1/3/1/8/131856158/5dd64e069.pdf'. This suggests a phishing or malicious redirection attack.

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.
