MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as a phishing lure due to its image-only nature and small file size, typical of a screenshot designed to hide clickable links. The ClamAV detection and embedded URLs further support its malicious classification. While no scripts were extracted, the presence of external URLs suggests the document is intended to redirect the user to a malicious site for further exploitation.
