Windows Event ID 4723 - An attempt was made to change an account's password

Introduction

This event is generated every time a user attempts to change their password.
Note: Event ID 4724 is recorded every time an account attempts to reset the password for another account.

If the new password fails to meet the domain password policy (or local password policy for local user accounts) then a failure event is recorded.

While changing the password, if a user misspells their old password, then event ID 4771: Kerberos pre-authentication failed or event ID 4776: The computer attempted to validate the credentials for an account will be generated on the domain controller.

The Subject\Security ID and Target Account\Security ID fields should match in a normal environment.

user-management-reports

Security ID: The SID of the account that made an attempt to reset the Target Account's password.

Account Name: The name of the account that made an attempt to reset the Target Account's password

Account Domain: The Subject's domain or computer name. Formats may vary to include the NETBIOS name, the lowercase full domain name, or the uppercase full domain name.
For well-known security principals, this field is "NT AUTHORITY," and for local user accounts, this field will contain the computer name that this account belongs to.

Logon ID: The logon ID helps you correlate this event with recent events that might contain the same logon ID (e.g. event ID 4624).

Security ID: The SID of the account for which the password reset was requested.

Account Name: The name of the account for which the password reset was requested.

Account Domain: The Target Account's domain or computer name. Formats could vary to include the NETBIOS name, the lowercase full domain name, or the uppercase full domain name.
For well-known security principals, this field is "NT AUTHORITY," and for local user accounts, this field will contain the computer name that this account belongs to.

Privileges: The list of user privileges used during the operation.

Monitoring event ID 4723.

  • If you have several IT administrators that share a common account for all administrative purposes (which isn't recommended), then you would need to track this event back to a logon event with a matching Logon ID to identify the source workstation or server from which this account's password was changed.
  • Monitor event ID 4723 for accounts that have Target Account/Security ID corresponding to high-value accounts, including administrators, built-in local administrators, domain administrators, and service accounts.
  • Mointor event ID 4723 for accounts that have to be monitored for every change. This list can vary between enterprises and industries.
  • Monitor all 4723 events for local accounts, because their passwords usually do not often change, and this could serve as an indicator of malicious activity.
  • Monitor event ID 4723 for accounts for which the password should never be changed (for example, service accounts).
  • This is a critical event and since the volume of such events is considerably small in a normal environment, it's recommended that you monitor and set up alerting for all password change events.

The need for an auditing solution.

Auditing solutions like ADAudit Plus offer real-time monitoring, user and entity behavior analytics, and reports; together these features help secure your AD environment.

Around the clock, real-time monitoring.

Although you can attach a task to the security log and ask Windows to send you an email, you're limited to simply getting an email whenever event ID 4723 is generated. Windows also lacks the ability to apply more granular filters that are required to meet security recommendations.

For example, Windows can send you an email every time event ID 4723 is generated, but it can't tell the difference between regular and high-value accounts. Receiving alerts specifically for high-value accounts reduces the chance of missing out on critical notifications amongst the heap of false-positive alerts.

With a tool like ADAudit Plus, not only can you apply granular filters to focus on real threats, you can receive real-time notifications via SMS, too.
