MITRE ATT&CK

T1566.001 Spearphishing Attachment

The document contains multiple embedded URLs and a prominent link in its body text, all related to game hacks and cheats, suggesting a lure for users to download potentially malicious content or visit phishing sites. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and callback lures further supports a malicious intent. No scripts were extracted from this sample.

Nyx PDF Classifier malicious score 0.9980

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.
