MITRE ATT&CK

T1059.001 PowerShell

The critical ClamAV detection and multiple PDF-specific heuristics, including PDF_EVAL and PDF_FROMCHARCODE, indicate malicious intent. The embedded JavaScript stream, named 'javascript_obj0013_001.js', is highly suspicious due to obfuscation. This script is likely responsible for downloading and executing a second-stage payload, a common dropper behavior.

Heuristics 6

ClamAV: Pdf.Dropper.Agent-7251988-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Dropper.Agent-7251988-0
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
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.
String.fromCharCode low PDF_FROMCHARCODE

String.fromCharCode found — used to construct payload strings dynamically. Common in benign JavaScript libraries for codepoint manipulation, so this alone is informational; weaponised use is also caught by the dedicated fromCharCode-stage and exploit-shape rules. (matched inside decoded stream)
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.
