MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URL that advertises free spins for the game Coin Master, a common lure for phishing or malware distribution. The ML classifier strongly flagged this PDF as malicious. While no scripts were extracted, the presence of the external URI and the lure suggest the document is intended to trick the user into downloading a second-stage payload.
