MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript and exhibits characteristics indicative of the CVE-2010-0188 exploit, specifically related to CCITTFaxDecode and XFA. The high number of streams suggests obfuscation or heap spraying techniques. The embedded JavaScript is likely responsible for triggering the exploit and executing a malicious payload.

Heuristics 5

  • CCITTFaxDecode + TIFF/XFA exploit prep — LibTIFF CVE-family indicator high CVE related PDF_CCITT_CVE_2010_0188_RELATED
    PDF uses /CCITTFaxDecode together with TIFF/XFA exploit-preparation markers such as rawValue image-field assignment, TIFF data, or heap-spray JavaScript. This matches the delivery pattern for Adobe Reader LibTIFF/CCITTFax parser exploit families, including CVE-2010-0188, but does not prove the exact malformed TIFF primitive.
  • Unusually high stream count medium PDF_MANY_STREAMS
    PDF contains 501+ stream objects — may indicate heap spray or heavy obfuscation
  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • 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.
