MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

This PDF file was flagged as malicious by an ML classifier and contains embedded JavaScript. The JavaScript is heavily obfuscated, but static analysis indicates the presence of `eval()` calls, suggesting it attempts to execute arbitrary code. The extracted artifact `javascript_obj0013_000.js` is likely the source of this malicious script. The obfuscation and use of `eval()` are common techniques for delivering second-stage payloads.
