What it detects

This rule detects command lines writing to the reconnaissance output file Domain_users_light.txt associated with AdFind based Active Directory enumeration. This behavior matches intrusions that rename AdFind to a.logs and dump domain user objects for targeting. Structured directory enumeration output is a discovery indicator that commonly precedes lateral movement and Kerberoasting.
