MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains multiple embedded URLs, including one pointing to 'netcdn.co', which likely serves as a download link for a malicious payload. The document body and extracted URLs suggest a lure related to obtaining free items or currency for the game Roblox, a common tactic for distributing malware. The ML classifier also strongly indicated maliciousness.
