T1204.002 Malicious File
The critical ClamAV heuristic identified the file as 'Pdf.Dropper.Agent-7212606-0', indicating a known malicious PDF dropper. The presence of embedded JavaScript, confirmed by multiple heuristics, strongly suggests that the script is responsible for downloading and executing a secondary payload. The document body content is unreadable, but the combination of the ClamAV detection and the JavaScript suggests a typical dropper behavior.

-
JavaScript action low PDF_JAVASCRIPTPDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
syncAnnotScan annotation-staging primitive low PDF_FOXIT_SYNCANNOTSCANPDF JavaScript calls syncAnnotScan() — a no-op annotation-enumeration primitive used by exploit-kit JavaScript to stage payload reads from annotation /Subject fields before eval(). Not a vulnerable sink itself; rarely seen in legitimate PDFs. (matched in decompressed stream)
