MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded links and a visual call-to-action, strongly suggesting a phishing or malware distribution attempt. The primary URL, https://netcdn.tw/app/431946152/roblox-shinobi-life-max-hack-2021-game-hack, is presented as a download for game hacks, which is a common lure for distributing malware. While no scripts were directly extracted, the ML classifier and heuristic firings indicate malicious intent, likely to lead the user to download a second-stage payload.
