MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. A critical heuristic, PDF_EVAL, points to the use of eval() for code execution. The ML classifier and ClamAV detection strongly suggest malicious intent, specifically identifying it as Pdf.Exploit.Agent-35587. The reconstructed string 'tp.splt' from the document body is likely a critical part of the exploit's functionality, possibly related to payload delivery or execution.

ClamAV: Pdf.Exploit.Agent-35587 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-35587
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.

Extracted artifacts 2
