MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

This PDF file is identified as malicious due to the exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader's handling of XFA forms. The exploit targets a LibTIFF vulnerability within the XFA processing, indicating an attempt to achieve arbitrary code execution. The presence of an embedded script payload further supports this, suggesting the file is designed to download and execute a secondary stage. No specific family could be identified, but the exploit vector is clear.

Heuristics 5

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188

PDF contains the CVE-2010-0188 exploit template: XFA JavaScript heap-spray setup, a generated TIFF image payload, and assignment of that TIFF data to an XFA image field rawValue to trigger Adobe Reader's LibTIFF parser.
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
Embedded script payload in PDF stream low 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 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.
