MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell

The PDF file contains embedded content and XFA forms, which are often used to deliver exploits. The presence of a PDF_UNESCAPE heuristic firing and an embedded script payload indicates an attempt to execute malicious code. The embedded file 'embedded_file_obj0008.bin' is highly suspicious and likely contains the secondary payload. The script's intent is to exploit a PDF viewer vulnerability, leading to the execution of the embedded file.

Heuristics 7

XFA form contains risky executable script high CVE related PDF_XFA_SCRIPT

PDF 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_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits
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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One 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.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
