MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicated maliciousness, and the PDF contains multiple external URIs pointing to other PDF files hosted on various domains. The document body discusses environmental damage, likely a lure to entice users to click on the embedded links. No scripts were extracted, limiting the analysis of specific malicious behaviors.
