MITRE ATT&CK

T1204 Malicious File

The PDF file contains embedded JavaScript, which is a common technique for exploiting vulnerabilities in PDF readers. The ClamAV signature 'Pdf.Exploit.Pdfka-9' strongly suggests the presence of an exploit. The embedded JavaScript is likely responsible for delivering a secondary payload or initiating malicious actions.

Heuristics 3

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.
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.
