MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a visual download button lure, strongly suggesting a phishing or scam attempt. The primary URL, https://netcdn.xyz/app/406889139/free-spin-link-of-coin-master-game-hack, is likely intended to lead the user to a malicious site. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a malicious workflow designed to trick users into visiting potentially harmful websites.
