MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that promote free in-game currency for popular games, acting as a lure. The primary malicious URL, http://netcdn.co/app/431946152/free-roblox-avatar-game-hack, is directly linked to the lure content and is flagged by heuristics. The ML classifier also strongly indicates maliciousness, suggesting the document is designed to trick users into downloading a payload.
