MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This technique is commonly used to distribute malware or redirect users to phishing sites. The ClamAV detection 'Pdf.Dropper.Agent-7908497-0' further supports its malicious nature. No scripts were extracted from this sample, and the document body was heavily obfuscated, preventing a more detailed analysis of the lure.
