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

The PDF file contains an embedded script payload and an embedded file, flagged by heuristics as malicious. The ML classifier strongly indicates maliciousness. The embedded URL, http://the-eponymous.net/GB2dbx0vQpM0T3rF0iDOD03V9L0Df660bkyU0nVPd0uG9d0r3lJ08BTt09Aa70Zo4L0hM5x16tty0Cwr00Qpr60zDW10QxLY120Sj0MS4v02JXD0IP970nvb811pST0Zbfe0CF960Xb7e0QrwT17rTA0JpqR0z5gK0eaGo00zHB0bwcL0rlYC0zJ3w0JcqD0hsOP09lQC0DhTB0Mb6k12Zjw06OTO0gOM20hcAw0EO5K0d93m0k4uU/r80AJg2F5L.exe?IuJxb8o2UHfaahebOF4b=1blzid5cO3L0B0by&quot, is likely used to download and execute a secondary payload. The presence of XFA forms and embedded scripts suggests a delivery mechanism common for exploiting PDF vulnerabilities.

Heuristics 5

  • 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
  • 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.
