MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and references to game hacks and cheats, indicating a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs and the document's theme suggest it's designed to trick users into visiting malicious sites or downloading malware, likely via a spearphishing attachment vector.

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.
