MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

This PDF file exploits the CVE-2010-0188 vulnerability in Adobe Reader via XFA forms. The embedded JavaScript, identified by ClamAV as Js.Exploit.HTML-30, likely acts as a stager to download and execute a second-stage payload. The presence of XFA numeric JavaScript and a long encoded blob further supports this conclusion.

Heuristics 7

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: Js.Exploit.HTML-30 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Js.Exploit.HTML-30
XFA numeric JavaScript stager high PDF_XFA_NUMERIC_JS_STAGER

PDF XFA script reconstructs a hidden JavaScript stage from numeric field data or a character table, then evals the result. The decoder is gated on XFA script, numeric staging, and recovered exploit-like JavaScript or shellcode markers.
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: PSEOF. 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.
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.
