MITRE ATT&CK

T1566.001 Spearphishing Attachment

The document's body and numerous extracted URLs promote 'Free Robux' and related gaming hacks, strongly suggesting a scam or phishing lure. The heuristic 'SE_LOLBIN_RUN_COMMAND' indicates the presence of command execution indicators within the document text, potentially related to obfuscated JavaScript or other scripting. While no explicit scripts were extracted, the ML classifier and URI findings point to malicious intent.

Nyx PDF Classifier malicious score 0.6193

Heuristics 4

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.
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.
