MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

This PDF document was identified as malicious by an ML classifier and contains numerous links to external websites, many of which appear to be part of a scam or phishing operation related to free in-game currency. The document body explicitly mentions 'Roblox Cheat Engine Jailbreak' and includes URLs pointing to potential downloads or scam sites. The presence of a 'Download Now' lure further supports the 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.
