Pulling a backup out of iCloud is one of the more technically demanding jobs in cloud forensics. An iCloud backup is not a single, ready-to-download file; instead, it is assembled from a large number of separate fragments that have to be collected and stitched back together into a coherent backup. Recent changes to Apple’s communication protocols broke things for everyone except Apple themselves, meaning that we had to rework the underlying extraction logic. This is documented in Elcomsoft Phone Breaker 11 Restores iCloud Access.

A few days ago we wrote about YellowKey, the newest entry in what has become a remarkably long list of BitLocker bypasses. That article walked through one specific attack with a practical workflow. This follow-up steps back and surveys the broader landscape: where BitLocker has been broken before, where it is still broken today, and what an investigator should expect to encounter on a seized Windows machine in 2026.

On May 12, 2026, a researcher operating under the handles Chaotic Eclipse and Nightmare-Eclipse dropped a working proof-of-concept on GitHub for a Windows zero-day called YellowKey. In short, it lets anyone with brief physical access to a BitLocker-protected Windows 11, Windows Server 2022, or Windows Server 2025 machine pop a command prompt with full read access to the encrypted volume. No password. No recovery key. No TPM sniffing rig. A USB stick and a key combination during reboot.

Over the years, we have published several articles about the extraction agent. However, the underlying technology changes quickly, and incremental changes often have significant cumulative effects. As a result, many of our older posts are no longer relevant and can be misleading if followed to the letter today. While last year’s recap, Installing and Troubleshooting the Extraction Agent (2025), remains a solid foundation for general setup, it does not account for the most recent hardware and software developments. This article serves as the definitive point of reference, providing an up-to-date recap of everything you need to know about the extraction agent as of May 2026.
