MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple embedded URLs that lead to sites offering game hacks and free in-game currency, a common lure for phishing and malware distribution. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent to trick users into downloading unwanted or harmful content. No scripts were extracted, but the document's structure and embedded links indicate a social engineering attack.

Heuristics 4

QR-code redirect lure medium SE_QR_LURE

Document instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
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
