MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple lures related to "free TikTok followers" and "game hacks", directing users to external URLs. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs suggests an attempt to redirect users to potentially malicious sites or download further payloads. No scripts were extracted from this sample, but the overall pattern indicates a phishing or scam attempt.

Heuristics 4

  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
  • 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.
