T1204.002 Malicious File
The critical ClamAV heuristic identifies the file as 'Pdf.Dropper.Agent-7263123-0', 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 deobfuscated JavaScript, though large, likely contains the logic for this malicious action. The document body is unreadable, but the technical indicators point to a dropper function.

ClamAV: Pdf.Dropper.Agent-7263123-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Dropper.Agent-7263123-0
-
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)
