T1059.007 JavaScript
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The PDF sample contains embedded JavaScript, indicated by PDF_EMBEDDED_SCRIPT_PAYLOAD and EXTRACTED_FILE_STATIC_TRIAGE heuristics. The presence of PDF_EVAL and PDF_UNESCAPE calls suggests the script is obfuscated and designed to execute arbitrary code. The ML classifier strongly flags this PDF as malicious. The embedded script likely serves to download and execute a second-stage payload, aligning with common malicious PDF attack patterns.

Heuristics 5
-
eval() call high PDF_EVALeval() found — commonly used for obfuscated exploit execution
-
unescape() call high PDF_UNESCAPEunescape() found — often used to decode shellcode in PDF JS exploits
-
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
-

-
