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

The PDF document contains a prominent link to 'netcdn.co' which is associated with downloading an application promising free Robux. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure reinforces the intent to trick the user into executing a payload. The document body and embedded URLs suggest a social engineering lure related to in-game currency.
