T1204.002 Malicious File
The PDF contains embedded JavaScript, including an eval() call and ASCIIHexDecode filter, indicating an attempt to obfuscate malicious code. The presence of 'CYsoVyap.swf' suggests the potential execution of a Flash object, which could be used to deliver a secondary payload. The heuristics indicate multiple PDF-specific exploit indicators.
Heuristics 5
-
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
