MITRE ATT&CK

T1204.002 Malicious File T1566.001 Spearphishing Attachment

The PDF file contains an embedded XFA form and triggers critical heuristics for CVE-2010-0188, indicating exploitation of a known Adobe Reader vulnerability. This exploit is designed to execute arbitrary code, likely leading to the download and execution of a second-stage payload. The embedded artifact and ClamAV detections further confirm 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.
ClamAV: Pdf.Exploit.CVE_2010_0188-10 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.CVE_2010_0188-10
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
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
