T1204.002 Malicious File
The PDF contains embedded JavaScript and a RichMedia (Flash) object, indicating an attempt to exploit vulnerabilities. The ML classifier strongly suggests malicious intent. The embedded file 'sploit.swf' is likely a Flash exploit. While the embedded URL is confirmed benign, the presence of exploit-related artifacts points to a malicious PDF designed to deliver a second-stage payload.

- Nyx PDF Classifier malicious score 1.0000
Heuristics 5
-
RichMedia (Flash) high PDF_RICHMEDIAPDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
-
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.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://adobe.com/AS3/2006/builtin
