MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a call-to-action phrase, strongly suggesting a phishing or social engineering attempt. The ML classifier also flagged this PDF as malicious with high confidence. The primary URL, https://netcdn.online/app/406889139/coin-master-free-spins-link-2021-ios-game-hack, likely leads to a download of a second-stage payload. No scripts were extracted from this sample.
