MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a signature indicating it is a phishing trojan. It contains an embedded URI pointing to a URL that appears to be a search result, likely a lure to trick users into visiting a malicious site. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, a tool often used to create PDFs from web content, further supporting the lure-based attack pattern.
