T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple embedded URLs and a clear lure for a "Coin Master Hack 2021 Download". The heuristic 'SE_SECRET_RECOVERY_LURE' indicates the document attempts to solicit sensitive information like private keys or passwords, which is a strong indicator of a phishing or scam attempt. The presence of external URIs and the ML classifier's high confidence further support the malicious nature of this file.
