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

The PDF document contains a heuristic firing indicating it links to known malicious redirector infrastructure, specifically a URL related to a 'princess diaries soundtrack rar' lure. It also exhibits characteristics of a PDF link farm, with numerous external links, many of which point to PDF files hosted on various domains. The primary malicious URL identified is https://ttraff.link/wix?keyword=princess+diaries+soundtrack++rar, which likely serves as the initial entry point for a download or further redirection.

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.
    URL https://ttraff.link/wix?keyword=princess+diaries+soundtrack++rar
