MITRE ATT&CK

T1059.007 JavaScript T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript that utilizes eval() and string concatenation to obfuscate its functionality. This script is designed to exploit a known PDF vulnerability, as indicated by the 'PDF_JS_EXPLOIT_CLUSTER' heuristic. The primary purpose of the script appears to be downloading and executing a second-stage payload, consistent with dropper malware.
