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://gettraff.ru/aws?keyword=pm+awas+yojana+form+in+hindi+pdf, is the primary indicator of malicious intent. While no scripts were extracted, the PDF structure and the malicious URL strongly suggest a phishing or malware delivery attempt.

  • Embedded URL info EMBEDDED_URL
