MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body contains references to popular online games like PUBG and Coin Master, along with a URL that appears to be a download link for game cheats. The presence of embedded URLs and a heuristic indicating a visual download button suggests an attempt to trick the user into downloading a second-stage payload.
