MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains embedded URIs that point to external websites, with one heuristic specifically flagging it as a PDF dropper. While no scripts were extracted, the presence of multiple unknown URLs suggests an attempt to redirect the user to potentially malicious sites. The ClamAV detection further supports its malicious nature.
