MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded JavaScript, a common technique for initiating malicious actions. ClamAV detections for 'Pdf.Malware.Agent-6312717-0' and 'Doc.Downloader.Donoff-10030369-0' strongly suggest that the embedded JavaScript is designed to download and execute a secondary payload. The PDF itself appears to be a lure, as indicated by the 'PDF_IMAGE_ONLY_LURE' heuristic, lacking readable text content.

Heuristics 6

ClamAV: Pdf.Malware.Agent-6312717-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Malware.Agent-6312717-0
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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
PDF paints image(s) but contains no text operators info PDF_IMAGE_ONLY_LURE

PDF has 1 image XObject(s) and the content stream contains no text-emitting operators (BT/ET, Tj, TJ, ', ") in either raw bytes or decompressed streams — this is the screenshot-as-PDF pattern used to bypass text-based scanners and to deliver instructions purely through rendered pixels. It is informational unless paired with invisible links or risky URI context.
