MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Dropper.Agent-1828971' strongly suggests this is a dropper. The embedded JavaScript, although obfuscated, likely facilitates the download and execution of a secondary malicious payload, a common technique for PDF-based malware delivery. The file size and heuristic firings align with a dropper functionality.

Heuristics 5

ClamAV: Pdf.Dropper.Agent-1828971 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Dropper.Agent-1828971
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)
