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

The PDF contains embedded URLs and document body text that promote game cheats and hacks, specifically mentioning 'Coin Master'. The presence of a 'download button' heuristic and a high-confidence ML classifier further supports a malicious intent to redirect users to potentially harmful content. The primary attack vector appears to be luring users via a malicious link to download unwanted software.
