Logged-On User Password Change Via Ksetup.EXE

Sigma Rules

View Source
Summary
This detection rule is designed to monitor and alert on the use of the 'ksetup.exe' executable, specifically when it is invoked to change the user password. 'ksetup.exe' is a command-line utility in Windows that is typically used for configuring Kerberos settings. The rule captures instances where the command line contains the '/ChangePassword' parameter, indicating a password change operation for the currently logged-on user. Additionally, it examines process creation logs for instances of 'ksetup.exe', checking if the process's image name ends with 'ksetup.exe', or if the 'OriginalFileName' matches 'ksetup.exe'. This method effectively detects unauthorized or unusual password change requests that could indicate malicious activity or user misconfiguration, thereby providing an essential control in the incident response workflow.
