Type Name Severity Module Data source / event ATT&CK
BIOC Active directory enumeration using built-in nltest.exe Nltest.exe is a command-line tool used for network administrative tasks, and can be used to gather information about domain controllers and users. Informational Platform Analytics Process execution Discovery
Analytics BIOC Administrator groups enumerated via LDAP An LDAP search query that collects information about administrators was executed. This may be indicative of Active Directory domain enumeration, which can be used to perform attacks against the organization. Informational Platform Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics BIOC Cached credentials discovery with cmdkey Cmdkey is a built-in Windows tool that can cache domain user credentials for use on specific target machines, Attackers can access cached user credentials using cmdkey /list. Low Platform Analytics XDR Agent Credential Access, Discovery
BIOC Enumeration command called by commonly abused CGO Some malware uses these commands for reconnaissance. Informational Platform Analytics Process execution Discovery
BIOC Enumeration of Windows services from public IP addresses Attackers may enumerate internet-facing services which use Windows protocols; as these services were not meant to be exposed to the internet, they may be attacked by enumerating users, brute-forcing passwords and through exploits. Informational Platform Analytics Dml connection Discovery
Analytics BIOC LDAP search query from an unpopular and unsigned process An unpopular and unsigned process performed an LDAP search query. This may be indicative of LDAP enumeration. Low Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics BIOC LDAP traffic from non-standard process 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. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Local account discovery One of several local account discovery commands were executed. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Local user enumeration via SAMR A user enumerated local users via SAMR. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics Possible LDAP enumeration by unsigned process An unsigned process performed multiple different LDAP search queries. This may be indicative of LDAP enumeration. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
BIOC Possible Oracle enumeration via Oscanner The Oscanner Oracle framework performs enumeration of SIDs, account roles, privileges, hashes, and more. Attackers may attempt to gather this information during the reconnaissance phase. Low Platform Analytics Process execution Discovery
BIOC Possible user enumeration via /etc/passwd Attackers may enumerate users by reading the /etc/passwd file. Informational Platform Analytics Process execution Discovery
BIOC Possible user enumeration via finger The Linux 'finger' command performs user enumeration, which attackers may attempt to gather during the reconnaissance phase. Informational Platform Analytics Process execution Discovery
BIOC PowerShell dumps users and roles from Exchange server PowerShell is used to dump users and roles from Exchange servers, this may indicate malicious behavior (e.g. the SolarStorm campaign). Medium Platform Analytics Process execution Discovery
Analytics Rare LDAP enumeration Possible LDAP enumeration with a rare combination of queries. Low Platform Analytics Palo Alto Networks Firewall EAL Logs Discovery
BIOC SharpHound LDAP query SharpHound is a BloodHound ingestor that performs LDAP queries to enumerate Active Directory. Medium Platform Analytics Windows event log Discovery
BIOC Sudoers discovery Attackers may enumerate the sudoers file or use the 'sudo -l' command to discover user privileges. Informational Platform Analytics Process execution Discovery, Privilege Escalation
BIOC Suspicious access to /etc/shadow Attackers may enumerate or modify user accounts by accessing the /etc/shadow file. Informational Platform Analytics File Discovery
Analytics BIOC Suspicious LDAP search query executed A suspicious and unpopular LDAP search query was executed. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. Low Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics Suspicious reconnaissance using LDAP A process executed multiple suspicious LDAP search queries. This may be indicative of LDAP enumeration. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics BIOC Uncommon access to /etc/passwd A process made an uncommon attempt to access /etc/passwd. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery, Credential Access
Analytics BIOC Uncommon attempt at grabbing credentials from a sensitive file A process made an uncommon attempt to access a file that may contain sensitive information. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access, Discovery
Analytics BIOC Uncommon user management via net.exe The net.exe command is used to add, delete, and otherwise manage the users on a computer. Adversaries may attempt to use the command to discover or add local and domain user accounts. Informational Platform Analytics XDR Agent Discovery, Persistence
Analytics User and Group Enumeration via SAMR The endpoint performed unfamiliar SAMR querying activity to a domain controller. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery
Analytics BIOC User discovery via WMI query execution Attackers or malware may use WMI queries to list the users of a host, and potentially its owner. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Execution, Discovery
