T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded URLs and text that promote free game currency and hacks, indicating a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to a download site. The document body explicitly mentions 'Free Robux Redeem Card Codes 2021' and includes a primary URL for downloading an application.
