MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ClamAV heuristic identified this PDF as a phishing trojan. The embedded URLs, although some are marked as benign, suggest an attempt to redirect the user to malicious content. The PDF structure itself, generated by wkhtmltopdf, does not contain readable text, indicating it's likely a container for malicious links rather than a content-based lure.
