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

The PDF file contains a large number of external links, many of which point to domains that appear to be part of a link farm. The document body itself contains text that seems to be a lure, referencing 'cheat codes', and also includes the URL 'http://jordandecesare.com/uploads/1/3/1/3/131379230/131379230.html#tactics+ogre+let+us+cling+together+psp+cheat+codes'. This suggests a malicious intent to redirect users to potentially harmful websites.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
