MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded links, identified as a link farm, that direct users to pages offering game hacks and cheats for popular games like Roblox and Coin Master. The document body explicitly mentions 'How To Get My Hacked Account Back On Roblox' and includes a URL pointing to a similar topic. This suggests a phishing or scam attempt designed to trick users into visiting malicious sites, potentially leading to credential theft or malware download. Although no scripts were explicitly extracted, the PDF structure and embedded links are indicative of malicious intent.

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.
