MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The file is a PDF containing embedded JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ML classifier and ClamAV detection strongly suggest malicious intent, specifically identifying it as 'Pdf.Exploit.Dropped-94'. The embedded JavaScript, which is a large stream, is likely responsible for exploiting a vulnerability within the PDF reader to download and execute a secondary payload. The document body content is not indicative of a specific lure and appears to be metadata or boilerplate text.
