MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a lure for a "Coin Master Hack Online" and a visual download button, strongly suggesting a social engineering attempt to trick the user into downloading a malicious payload. The embedded URL points to a suspicious domain, likely hosting the secondary stage. No scripts were extracted, but the ML classifier indicates a high probability of maliciousness.
