MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains multiple embedded URLs and a call-to-action to access a 'TIKTOK GENERATOR', which is a common lure for phishing or malware distribution. The ML classifier also flagged this PDF as malicious. The presence of MFA lure heuristics suggests an attempt to harvest session tokens or credentials. No scripts were extracted, but the embedded URLs point to potentially malicious content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8060

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.
