T1566.001 Spearphishing Attachment

The PDF document contains an embedded URI and multiple other URLs that lead to pages offering "free spins" or "free coins" for games like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, indicating it likely serves as a lure to a phishing or scam website. The presence of these external links suggests an attempt to redirect the user to a malicious site, potentially for credential harvesting or malware distribution.
