T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains a prominent link to 'netcdn.xyz' disguised as a guide for 'Coin Master Free Tips'. The presence of a 'download button' heuristic and the ML classifier's high confidence score suggest malicious intent. The document body, though partially corrupted, also contains the malicious URL, reinforcing the lure to a potentially harmful resource.
