The PDF document contains a link farm designed to trick users into downloading files, with one heuristic specifically flagging a remote-support tool lure. The embedded URL 'http://raisengine.com/ZG93bmxvYWR8eXQ5TVRSeGMzeDhNVFkxTmpjM01UZ3hPSHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA?enthuse=inflammables=spectrum=littoral=ZmluYWwgZHJhZnQgOCBzZXJpYWwga2V5Z2VuIGFuZCBjcmFjawZml' is likely a payload delivery mechanism. The document body was unreadable, preventing a more detailed analysis of the lure.

Heuristics 4

  • 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.
  • Remote-support tool lure high SE_REMOTE_SUPPORT_LURE
    Document instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited document
  • 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.
