MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are hosted on domains associated with game hacks and cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious intent. The primary URL, http://netcdn.tw/app/431946152/hack-richest-roblox-account-deleted-game-hack, likely serves as the initial lure for a phishing or malware download campaign.
