T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a lure for free items, consistent with phishing or malware distribution. The ML classifier strongly flagged this PDF as malicious. The presence of MFA/one-time-code harvesting lures suggests an attempt to steal credentials or session tokens. No scripts were extracted, but the document body and embedded URLs point to a malicious intent.

Heuristics 4

MFA / one-time-code harvesting lure high SE_MFA_LURE

Document asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
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.
