MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains numerous embedded links, identified as a link farm, pointing to websites offering game hacks and cheats. The ML classifier strongly indicated maliciousness, and the presence of a download button lure reinforces the intent to trick users into navigating to potentially harmful external resources. While no scripts were directly extracted, the PDF structure itself facilitates the redirection to these malicious URLs.

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.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
