MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of external links, identified as a 'link farm' heuristic. The document body, though partially corrupted, contains text related to 'hacking' and 'robux', suggesting a lure for users interested in such topics. The presence of numerous SEO-themed links indicates an attempt to drive traffic to external sites, which could be for advertising, SEO manipulation, or hosting further malicious content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9971

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.
