MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a heuristic firing for a malicious redirector link pointing to 'https://ggtraff.ru/strik?keyword=divinity+original+sin+traits'. This URL is likely used to lure users to a malicious site. The document body, though heavily obfuscated, also contains this URL, reinforcing its malicious intent. No scripts were extracted, but the presence of a malicious redirector is sufficient evidence of a phishing or malware distribution attempt.
