MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV detection and the presence of embedded JavaScript strongly indicate malicious intent. The JavaScript action and embedded JS stream heuristics confirm the use of scripting within the PDF. The document body content is heavily obfuscated and unreadable, providing no further clues to the specific lure. The embedded JavaScript is likely responsible for exploiting a vulnerability to download and execute a secondary payload.
