MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document was identified as malicious by an ML classifier and contains a large number of external links, many pointing to other PDFs with similar themes of game cheats and hacks. The document body explicitly mentions 'Roblox Cheat Code' and includes URLs that likely lead to further malicious content or downloads, suggesting a link farm designed to distribute malware or phish for credentials. No scripts were extracted from this sample.

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.
