MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF file contains embedded JavaScript, identified by multiple heuristics including PDF_JAVASCRIPT and PDF_JS. The critical CVE_2007_5659 heuristic indicates the exploitation of a known vulnerability using a specific JavaScript technique involving the Collab.collectEmailInfo method. This technique is used to construct and execute JavaScript code, likely for downloading and executing a secondary payload. The presence of deobfuscated JavaScript files further supports this. The ClamAV detection also confirms its malicious nature.
