MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains multiple embedded URLs and a call-to-action lure, suggesting it is designed to trick users into downloading malicious content. The heuristic indicating a password-protected archive handoff further supports the malicious intent, as this is a common technique to bypass security filters. The ML classifier also strongly flagged this PDF as malicious.

Machine Learning

Nyx PDF Classifier malicious score 0.9980

Heuristics 4

Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
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.
