MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs that lead to sites offering 'Coin Master Hacks and Cheats'. The ML classifier flagged the PDF as malicious with high confidence. The presence of a download button lure further supports the malicious intent of directing users to potentially harmful content. No scripts were extracted, but the embedded links are the primary indicators of a phishing or scam attempt.
