MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell

The PDF contains embedded content and XFA forms, which are often used to deliver exploits. High-severity heuristics indicate the presence of risky executable scripts and an embedded file, suggesting an attempt to execute malicious code. The ML classifier strongly flags this PDF as malicious. The unescape() call is a common obfuscation technique used in PDF exploits.

Nyx PDF Classifier malicious score 1.0000

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.
