MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action button, strongly suggesting a phishing or scam attempt. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-link-today-new-game-hack, is likely intended to lead the user to a malicious site. While no scripts were explicitly extracted, the ML classifier and embedded URI heuristics indicate malicious intent, likely related to credential harvesting or malware distribution.
