MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The JavaScript action, likely embedded within a PDF exploit, suggests the file is designed to download and execute a second-stage payload. However, the specific functionality of the JavaScript is not fully discernible from the provided excerpt, leading to a lower confidence in family attribution.
