MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The PDF file contains an XFA form with an embedded script, which is a known vector for exploiting vulnerabilities. Specifically, the 'CVE_2010_0188' heuristic indicates exploitation of Adobe Reader's LibTIFF component. The embedded script is likely responsible for downloading and executing a second-stage payload. The ClamAV detection further confirms the malicious nature of the file.

Heuristics 6

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.
XFA form contains executable script high CVE related PDF_XFA_SCRIPT

PDF embeds an XFA form whose dataset contains a <script> or <xfa:script> block — XFA scripting has been the exploit primitive for several Adobe Reader RCEs (CVE-2010-0188 family, CVE-2018-4901, and others). Plain XFA without scripts is far less risky.
ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
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
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.
