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

The PDF file was flagged by an ML classifier as malicious. It contains embedded URLs pointing to external resources, likely intended to trick the user into downloading a payload. The document body, though partially corrupted, suggests a lure related to game hacks, further supported by the presence of a 'download button' heuristic.
