MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and text promoting a "Coin Master Hack Apk", strongly suggesting a lure for users to download potentially unwanted or malicious software. The ML classifier also flagged this PDF with high confidence. While no scripts were directly extracted, the presence of external URIs and the document's content indicate an attempt to redirect users to download sites.
