MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF is identified as a phishing lure due to its small size and image-heavy content, typical of a screenshot designed to hide a clickable element. The embedded URL points to a PDF hosted on a suspicious domain, likely serving as a secondary stage for the attack. ClamAV detection further supports the malicious classification.
