MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a heuristic firing for a malicious redirector link pointing to 'https://gettraff.ru/strik?keyword=searching+for+summer+answers'. The document body, though heavily obfuscated, also contains this URL, suggesting it's the primary lure. The ML classifier also flagged this PDF as malicious. The presence of embedded URLs and the redirector heuristic strongly indicate a phishing or malware delivery attempt.

Heuristics 2

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

Embedded URL info EMBEDDED_URL
