MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF that contains an embedded URI pointing to a URL that appears to be a lure for downloading further malicious content. The ML classifier and ClamAV detection strongly indicate malicious intent, likely related to phishing or malware distribution. No scripts were extracted, but the presence of external URIs suggests an attempt to download a second-stage payload.
