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

The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'ggtraff.ru'. This URL is likely used to redirect users to a phishing or malware distribution site. The ML classifier also flagged the PDF with high confidence, and ClamAV detected it as a phishing trojan. The embedded URL is designed to impersonate a legitimate platform, likely as a lure.
