MITRE ATT&CK

T1204.002 Malicious File

The PDF was flagged by multiple high-confidence heuristics, including a specific 'PDF metadata JavaScript eval stager' and a critical ClamAV detection for 'Pdf.Exploit.Dropped-94'. The presence of embedded JavaScript streams and actions strongly suggests the file is designed to exploit vulnerabilities within the PDF reader. The ML classifier also provided a near-perfect score for maliciousness. The embedded JavaScript is likely responsible for executing the exploit and potentially downloading a second-stage payload.

ClamAV: Pdf.Exploit.Dropped-94 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-94
PDF metadata JavaScript eval stager high PDF_METADATA_EVAL_STAGER

PDF JavaScript reads document metadata fields such as title, subject, or producer, decodes character data with parseInt/String.fromCharCode style helpers, and evals the recovered stage. This is a high-signal exploit-kit staging pattern.
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.
