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

The PDF file contains a "D d 5e druid spells pdf" lure, which is a common tactic to entice users to click on links. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK indicates that one of the embedded links, specifically https://ttraff.ru/pify?keyword=d+d+5e+druid+spells+pdf, points to known malicious redirector infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic indicates a large number of external PDF links, suggesting a link farm designed to manipulate search engine results or distribute malicious content. The document body contains garbled text but the presence of the lure and the malicious redirector URL are strong indicators of malicious intent.

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.
  • Urgency / deadline lure low SE_URGENCY_LURE
    Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
  • 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.
