MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is identified as malicious by multiple engines, including ClamAV which flags it as Win.Exploit.Jailbreak-1. The embedded URL http://jailbreakme.com/wad.bin is highly suspicious and likely serves as a download location for a secondary payload. The PDF structure and heuristic firings indicate an exploit targeting a client execution vulnerability.

Heuristics 3

  • ClamAV: Win.Exploit.Jailbreak-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Exploit.Jailbreak-1
  • 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.
  • 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.
