MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains an embedded JavaScript payload, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. The PDF_EVAL heuristic suggests that the script is executed using an eval() call. The extracted JavaScript file, stream_000_off00000287.js, is likely responsible for downloading and executing a second-stage payload. The XFA form heuristic also points to a non-standard PDF structure often used for malicious purposes.

Heuristics 4

eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF 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.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
