MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL 'https://ggtraff.ru/strik?keyword=radio+shack+same+weather+radio+manual+12+262' is the primary indicator of malicious intent. While no scripts were extracted, the PDF structure and the presence of malicious URLs suggest an attempt to lure the user to a compromised site, likely for phishing or malware delivery.

  • Embedded URL info EMBEDDED_URL
