MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment

The file is a PDF containing obfuscated JavaScript, as indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Heuristics.PDF.ObfuscatedNameObject' further supports its malicious nature. The embedded JavaScript stream is likely responsible for executing the malicious payload, potentially involving the download and execution of a second-stage artifact. The document body was unreadable, preventing a more specific determination of the lure.
