T1059.001 PowerShell
T1204.002 Malicious File
The PDF document contains embedded JavaScript, identified by the PDF_XFA_SCRIPT and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. The script, extracted as 'stream_001_off00000334.js', is likely responsible for downloading and executing a secondary payload. The PDF_UNESCAPE heuristic indicates that the script content may be obfuscated. The presence of an embedded file and XFA form further supports the malicious nature of the document.
Heuristics 6
-
XFA form contains risky executable script high PDF_XFA_SCRIPTPDF embeds an XFA form whose script block contains exploit, submission/launch, or shell-execution primitives. Ordinary LiveCycle print/update scripts are left as generic XFA/JS signals unless stronger behavior is present.
-
unescape() call high PDF_UNESCAPEunescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
-
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.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
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.
