T1204.002 Malicious File: User Execution: Malicious File
The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, and PDF_EVAL. The eval() call within the JavaScript is a strong indicator of malicious intent, likely to execute arbitrary code. The presence of ASCIIHexDecode filter with exploit indicators further suggests an attempt to exploit a PDF vulnerability. The file's purpose is to leverage these elements to execute malicious code.
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
