MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, with a primary focus on luring users to download a "free coin master spin app hack". The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest it's designed to redirect users to download potentially unwanted or malicious software.
