MITRE ATT&CK

T1566.001 Spearphishing Attachment

The document contains a lure for free TikTok followers and prompts the user to click a link, which is a common tactic for phishing or malware distribution. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to redirect the user to a malicious site for credential harvesting or further payload delivery.

Machine Learning

Nyx PDF Classifier malicious score 0.9982

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.
