MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document contains numerous links to external websites, many of which are presented as "SEO links" pointing to game-related hacks and cheats. The document body, though partially corrupted, includes a URL that appears to be a direct download link for a "PUBG UC Hack App". The presence of a large number of external links and the ML classifier's high confidence score indicate a malicious intent to redirect users to potentially harmful content or downloads.
