MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, indicating a link farm designed to redirect users to potentially malicious websites. The presence of multiple PDF files in the URLs suggests a pattern of distributing further malicious content or phishing pages. While no scripts were directly extracted, the PDF structure and extensive URL list strongly suggest an attempt to exploit users via external resources.
