MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment

The PDF file was flagged by ClamAV with 'Heuristics.PDF.ObfuscatedNameObject', indicating a high likelihood of malicious intent. The presence of embedded JavaScript, identified by the 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics, strongly suggests that the file is designed to execute code. While the JavaScript content itself was not fully detailed, its presence in a heuristically detected malicious PDF points towards it being used to download and execute a second-stage payload.
