7.5 Updates

Patch Version 7.5.0.267 Released

January 6, 2026

    Before: AD monitor filtered AD events when attributes were accessed but not changed.

  • 408453 – High CPU utilization caused by Netwrix Threat Prevention agent
    Before: AD Monitor resolved objectClass using slow DirRead LDAP queries, causing elevated CPU usage.
    After: objectClass resolution has been moved to the agent, reducing CPU utilization.

  • 410279 – LSASS crash on Windows Server 2025
    Before: A single signature was used for PspApplyMitigationOptions candidate resolution, which could cause LSASS crashes with LSA Protection enabled during agent stop.
    After: A multi-signature approach has been implemented, including a dedicated signature for Windows Server 2025.

  • 410528 – Exchange SE SU4 support
    Before: Netwrix Threat Prevention agents did not support Exchange SE SU4.
    After: Exchange signatures have been extended to support Exchange SE SU4.

  • 411172 – .NET Framework requirement
    Before: Netwrix Threat Prevention console and agent installers checked for .NET Framework 4.7.0.

Patch Version 7.5.0.256 Released

November 25, 2025

PowerShell

  • Fixed an issue where Get-SIAgent and other PowerShell commands failed due to incorrect handling of DateTime values during gRPC serialization.

Windows Agent

  • Resolved a potential LSASS crash on Windows Server 2025 systems with the KB5068861 (2025-11) update installed.

Exchange SE

  • Added Microsoft Exchange SE support.

October 30, 2025

  • Fixed an issue where the ADMonitor version number was displayed incorrectly.

Patch Versions 7.5.0.244 / 7.4.0.273 Released

October 23, 2025

Issues Resolved

  • 400587: Upgraded the BouncyCastle cryptography library to the latest supported version to enhance security and maintain compliance with current encryption standards.
  • 405320: Added an index on the utcTimeLogged column in the NvEvent table to improve database query performance and event logging efficiency.

Patch Version 7.5.0.236 / 7.4.0.250 for Threat Prevention Agents Released

September 19, 2025

New builds of the Netwrix Threat Prevention agent (7.5.0.236 and 7.4.0.250) have been released to address an issue affecting DCSync blocking policies.

Summary

A bug affecting host filtering in DCSync blocking policies was introduced in agent builds released on or after August 13 (part of the August SUVP update). This issue could potentially interfere with Active Directory replication, especially in environments with blocking policies enabled. As a result, environments relying on these policies to prevent unauthorized replication attempts may experience Active Directory replication issues.

Recommended Action
  • Update agents to version 7.5.0.236 or 7.4.0.250 as soon as possible.
  • If updates cannot be applied immediately, we recommend disabling DCSync blocking policies temporarily to avoid replication disruption.
  • DCSync monitoring policies are not impacted and can remain enabled.
Issues Resolved
  • 401764: Multiple domain controllers experiencing replication issues after installing the September patch and latest DLL
  • 401934: Active Directory replication shared memory IPC overflow alerts

Patch Version 7.5.0.224 Released

July 31, 2025

394634: NTM | File System permission change events are sending the formatted value instead of the SDDL value
Resolved an issue where file system permission changes reported formatted values in event data, rather than SDDL format.

395156: Exchange: 25-07 .NET updates support
Threat Prevention now supports the July 25 .NET Framework updates for Exchange environments, ensuring compatibility and continued monitoring.

396765: NTP → NAM: No events after implementing TLS for AMQP output
Resolved an issue where no events were sent from Netwrix Threat Prevention to Netwrix Activity Monitor after enabling TLS for AMQP output.

Patch Version 7.5.0.218

July 17, 2025

Netwrix Threat Prevention Agent

Fixed issue 393085
On Windows Server 2025 only, LSASS may crash during the startup of Netwrix Threat Prevention Agent 7.5.0 when the Enterprise Password Enforcer (EPE) policy is enabled.

To address this issue, upgrade the Netwrix Threat Prevention Agent to version 7.5.0.218. No changes are required for other components.

Patch Version 7.5.0.212 and 7.4.0.221 Released
