MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent link to 'netcdn.tw' which is associated with a Minecraft hacking tool. The ML classifier also flagged this PDF as malicious with high confidence. The presence of these links and the lure of a 'download button' suggest the document's primary purpose is to trick the user into downloading potentially malicious software.
