"Chukwuemeka Amachukwu believed he was operating safely offshore when he targeted his victims, but he has now been held to account and now faces a serious sentence for his crimes," said US Attorney Jamie McDonald in a Monday press release.

Microsoft announced that IT administrators can now use quick machine recovery on Windows Server 2025 after installing the October 2026 security update. Quick machine recovery (QMR) lets IT admins fix critical boot failures with targeted Windows Update fixes without physical access to affected systems. When enabled, it boots into the Windows Recovery Environment (WinRE) and launches the QMR Tool if Windows 11 fails to start because of a configuration change or a new driver. It then sends crash data to Microsoft, which can remotely fix issues by adjusting settings or removing problematic drivers or updates. "With the October 2026 security update, quick machine recovery extends to Windows Server 2025," the company said in a message center update. "Quick machine recovery is designed to help restore devices experiencing widespread boot issues by using the Windows Recovery Environment (WinRE) to search Windows Update for applicable remediations."
