MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The sample is a PDF document that triggers the CVE-2010-0188 exploit, targeting Adobe Reader. This exploit is known to be used for arbitrary code execution. An embedded file was also detected, which is often used to deliver secondary payloads. The ClamAV detection further confirms its malicious nature.

Heuristics 6

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.Agent-21602 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-21602
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
PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED

The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSSyntaxError. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
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.
