MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

This PDF file was flagged as malicious by ClamAV and an ML classifier, indicating a high likelihood of exploit. The presence of embedded JavaScript, specifically an eval() call, suggests the execution of arbitrary code. The script is obfuscated, but the core functionality appears to be the execution of a second-stage payload, as indicated by the 'eval()' calls and the ML classifier's output. The reconstructed string 'Math.ceil(lhvUP/epcMHHkXb' is part of the obfuscated JavaScript.

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.
