MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text referencing "Coin Master Hack" and "free robux", strongly suggesting a lure to download potentially malicious content. The ML classifier also flagged this PDF with high confidence. The primary IOC is the URL http://netcdn.tw/app/406889139/coin-master-hack-version-2021-game-hack, which likely serves as the download location for the payload.
