MITRE ATT&CK

T1059.001 PowerShell T1566.002 Spearphishing Attachment

The PDF file exhibits characteristics of malicious intent, primarily due to the presence of obfuscated JavaScript. The ClamAV heuristic 'Heuristics.PDF.ObfuscatedNameObject' strongly suggests that this JavaScript is designed to exploit vulnerabilities. While the exact payload is not immediately clear from the static analysis, the obfuscation and the heuristic firing indicate a high likelihood of malicious activity, such as driving further exploitation or downloading additional malware.
