MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The file was identified as malicious by multiple engines, including ClamAV which flagged it as Pdf.Dropper.Agent-7206819-0. An embedded artifact was also detected as Win.Exploit.Jailbreak-1. The presence of an unknown URL, http://jailbreakme.com/wad.bin, suggests the PDF is likely a dropper intended to download and execute a secondary payload, aligning with exploitation for client execution.

  • ClamAV: Pdf.Dropper.Agent-7206819-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Dropper.Agent-7206819-0
  • 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.
