MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs pointing to sites offering game hacks and free in-game currency, indicative of a lure for malware downloads or phishing. The presence of a 'callback phishing phone lure' heuristic further suggests a social engineering attempt. While no scripts were explicitly extracted, the ML classifier flagged the PDF as malicious with high confidence, and the embedded URLs are strong indicators of a malicious workflow.

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.
