  • LDAP traffic from non-standard process Informational 4 variations

    LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization.

    Activation:

    ATT&CK tactics: Discovery (TA0007)
    ATT&CK techniques: Account Discovery (T1087)
    Required data: XDR Agent
    Attacker's goals: An attacker is attempting to enumerate Active Directory.
    Investigative actions: Make sure the process is not a scanner that implements its version of the protocol, and that the scanner use is for sanctioned purposes. For example, nmap enumerating LDAP. Make sure the process is not a sanctioned security product that creates standalone binaries for its use. For example, Illusive Network honeypots. Investigate the process to see if the high-level language used to implement the application is the source of the alert. Some high-level programming languages provide their protocol implementations. Examine the endpoint to see if it is infected with malware. If the parent-child chain of initiating processes has been infiltrated with a malicious replacement, then that replacement could be known malware.

    Variations

    LDAP traffic from reverse SSH tunnel

    Medium overridden

    LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. overridden

    LDAP traffic from non-standard and uncommon process

    Low overridden

    LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. overridden

    LDAP traffic from non-standard process executed under an unsigned causality actor in a commonly abused directory

    Low overridden

    LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. overridden

    LDAP traffic from an injected thread within a non-standard process

    Low overridden

    LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. overridden
