MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that directly promote downloading hacks for popular games, aiming to trick users into downloading malicious files. The ML classifier strongly indicated maliciousness, and the presence of multiple download lures reinforces this assessment. While no scripts were explicitly extracted, the PDF structure and embedded links suggest a potential for JavaScript execution or redirection to malicious sites.

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.
