MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a critical heuristic indicating exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader related to XFA forms and TIFF images. ClamAV also detected this file as Pdf.Exploit.Pidief-3. An embedded file was extracted, which is likely the secondary payload. The attack pattern is consistent with a malicious document designed to exploit a software vulnerability upon opening.

Heuristics 8

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

PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
ClamAV: Pdf.Exploit.Pidief-3 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Pidief-3
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.
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
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
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85

ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
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.
