MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains multiple embedded URLs, with a primary focus on 'coin master' and 'roblox' related lures, suggesting a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious workflow. The primary IOC is the external URI pointing to a suspicious domain, likely serving as a download or redirection point.
