MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The sample is a PDF document that contains embedded URLs and lures the user with promises of game cheats and free currency. The ML classifier and the presence of external URIs strongly indicate malicious intent. The document body, though heavily obfuscated, contains references to game hacks and a primary URL pointing to a potential download site, suggesting it's designed to trick users into downloading a second-stage payload.

Heuristics 4

Payment redirection / bank-detail change lure high SE_PAYMENT_REDIRECT_LURE

Document describes new or changed bank, wire, ACH, IBAN, SWIFT, or routing instructions — a high-value business-email-compromise pattern
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.
