While no scripts were explicitly extracted, the PDF structure and the malicious URL suggest an attempt to lure the user to a harmful site, likely for phishing or to download further malware. The ML classifier also strongly flagged this PDF as malicious.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
