The PDF contains embedded JavaScript and RichMedia (Flash) content, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, PDF_RICHMEDIA, and PDF_EVAL. The presence of ASCIIHexDecode filter with exploit indicators suggests an attempt to obfuscate malicious code. The embedded file 'aHemNBymoE.swf' is likely the payload or a component thereof. The eval() call within the JavaScript is a strong indicator of dynamic code execution, likely to exploit a vulnerability or download a secondary payload.
Heuristics 6
-
RichMedia (Flash) high PDF_RICHMEDIAPDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
-
eval() call high PDF_EVALeval() found — commonly used for obfuscated exploit execution
-
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEXHex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
-
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
