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

The PDF file contains a significant number of embedded links, with a critical heuristic firing indicating a link farm. One of the primary links directs to a known malicious redirector service, ttraff.cc, which likely serves to obscure the ultimate malicious destination. The document body itself is heavily corrupted, but the presence of the 'wow classic druid guide wowhead' string suggests a lure, possibly related to gaming content, to entice users to click the malicious links.

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.
