MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains lures for 'free tokens' and 'free robux', directing users to external URLs. The presence of a 'download button' heuristic and an external URI firing strongly suggests a phishing or scam attempt. The ML classifier also flagged this PDF as malicious with high confidence.

Nyx PDF Classifier malicious score 0.9969

Heuristics 4

QR-code redirect lure medium SE_QR_LURE

Document instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
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.
