DETECTION OVERVIEW

AdFind Activity

Risk Factors

Reconnaissance tools can make enumeration relatively easy to perform. AdFind is a legitimate tool that enables the enumeration of Active Directory (AD) information over LDAP. But AdFind has been associated with attack campaigns and ransomware. An attacker needs network access to the target domain controller and credentials to run AdFind. Enumeration activity typically does not negatively affect network performance, but attackers can leverage this information to find new targets in an attack campaign.

Attack Background

AD domain controllers (DCs) store valuable information about objects (such as users, hosts, groups, organizational units, and sites) and privilege levels. LDAP enables any domain user to submit LDAP queries to a DC and retrieve information. AdFind is an open-source command-line tool that contains prepackaged search filters and attributes designed to enumerate AD information over LDAP. An attacker runs AdFind on a compromised device, sending LDAP queries to a DC to retrieve information. This information helps the attacker identify targets across the network.

Mitigation Options

Apply the principles of least privilege to domain users to reduce the information users can enumerate through tools such as AdFind
Because securing LDAP servers can be difficult without compromising functionality, monitor and investigate unusual LDAP activity quickly to minimize potential damage
