MITRE ATT&CK

T1059.007 JavaScript T1566.001 Spearphishing Attachment

The PDF contains obfuscated JavaScript, flagged by multiple heuristics and a machine learning classifier. The script attempts to download and execute a second-stage payload, indicated by the string concatenation and eval calls within the script. The presence of a JavaScript stream and the ML classification strongly suggest malicious intent, likely delivered via spearphishing.
