MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a phishing and trojan detection. It contains an embedded URL that, while currently flagged as benign, is part of a lure to download a 'Python Crash Course PDF'. The PDF metadata indicates it was generated by wkhtmltopdf, a tool often used to create documents from web content, suggesting it might be a crafted lure rather than a legitimate document.
