MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to external PDF files, a technique often used for SEO manipulation or to distribute further malicious content. ClamAV and ML classifiers strongly indicate maliciousness, specifically flagging it as phishing-related. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to redirect the user to potentially harmful content.
