T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded links and a call-to-action phrase, strongly suggesting a phishing or scam attempt. The ML classifier and PDF link farm heuristics indicate malicious intent, likely to redirect users to sites offering fake game currency or cheats. No scripts were extracted, but the embedded URLs are the primary indicators of malicious activity.
