MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The document contains numerous URLs and text fragments related to game hacks and cheats, indicating a lure for users to download malicious content. The presence of 'cmd-hack-roblox-game-hack' and the ML classifier's high confidence score suggest malicious intent. While no scripts were directly extracted, the document's structure and embedded URLs point towards a phishing or social engineering attack aimed at tricking users into executing further malicious payloads.

Heuristics 3

  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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.
