MITRE ATT&CK
T1559.002 Component Object Model Hijacking
The PDF file contains embedded JavaScript and a RichMedia (Flash) object, both of which are commonly used to deliver malicious content. The ML classifier strongly indicates maliciousness. The embedded JavaScript and Flash file are the primary indicators of the attack vector, likely leading to further compromise.
Machine Learning
- 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
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
Extracted artifacts 2
