# 4.4.5.9

# Features

- Increased hardening of portions of functionality previously conducted by the Windows cryptography libraries are done conducted by the Cyber Crucible kernel driver.
    
    
    - This is both general hardening, and an increase in telemetry indicating possible attacks against Windows cryptography libraries and APIs.
- This is a milestone release from incremental releases found in 4.4.5.4 - 4.4.5.8, all aligned on the previous cryptography analysis hardening functionality.
    
    
    - Early telemetry indicates the failures in Windows certificate and cryptography libraries were legitimately responded to by Cyber Crucible.
    - It is unknown at this time what percentage of issues were due to exploitation vs a Windows core library bug. Please contact your Cyber Crucible representative to discuss further as necessary.

# Fixes

- Fixed some process reports incorrectly reporting the listed certificate as “not trusted”, due to Windows certificate library functionality loss.
