Detects the use of ntdsutil.exe to create an Install From Media (IFM) set, which copies the NTDS.dit file and registry hives to a specified folder. Adversaries often use this technique to stage Active Directory credentials for exfiltration, frequently using the C:\Windows\Temp directory as a staging area. The rule includes exclusions for common legitimate system management and backup agents.

This rule monitors for suspicious credential-related activity targeting ONVIF interfaces on network devices (such as IP cameras). It detects a pattern where a successful 'global.login' RPC authentication is quickly followed (within 300 seconds) by commands or RPC methods related to credential dumping or user enumeration (e.g., OnvifUser, GetUsers). This sequence is indicative of an adversary using legitimate access to gain unauthorized information from a device.

Detects the execution of the OnvifUser utility with the -u flag, a technique observed in post-exploitation scenarios on Dahua network video recorder (NVR) devices to dump cached credentials.

Detects Active Directory DCSync attempts by monitoring for Windows Security Event ID 4662 where the object properties contain GUIDs associated with directory replication services (DS-Replication-Get-Changes, DS-Replication-Get-Changes-All, and DS-Replication-Get-Changes-In-Filtered-Set). The rule excludes domain controller machine accounts and known legitimate service accounts used for synchronization or backup operations.

Detects the creation of a Volume Shadow Copy followed by an attempt to access or copy the Active Directory database file (ntds.dit) from the shadow copy. This pattern is commonly used by adversaries to perform offline credential dumping.

Detects the removal of the com.apple.quarantine extended attribute from a file followed by the execution of the macOS 'security' utility to dump or retrieve passwords from the Keychain within a 5-minute window. This sequence is indicative of an adversary attempting to bypass Gatekeeper-related restrictions on a potentially malicious tool, followed by unauthorized access to sensitive credentials stored in the Keychain.

This rule detects the execution of Mimikatz or the use of its common command-line arguments, which are indicative of credential dumping and post-exploitation activities. It monitors process creation events for the 'mimikatz.exe' binary or command-line patterns associated with credential theft techniques such as dumping LSASS memory, extracting passwords, or Kerberos ticket manipulation.

This rule detects potential credential dumping activities by monitoring for the execution of Mimikatz or command-line arguments associated with credential extraction (e.g., 'sekurlsa::logonpasswords'). Additionally, it monitors for suspicious process access attempts to 'lsass.exe' with specific high-privileged access masks often used by credential dumping tools to read process memory.

Detects evidence of potential credential dumping from the Local Security Authority Subsystem Service (LSASS) process. The rule monitors for two distinct behaviors: the use of MemProcFS with device memory access flags targeting a RAW file, and the creation of files containing 'lsass.exe', 'minidump', and 'readme.txt' in their paths or filenames, which is characteristic of certain post-exploitation toolkits that harvest LSASS memory.

Detects attempts to perform a DCSync attack by monitoring for Windows Event ID 4662 where sensitive Directory Replication Service (DRS) rights are requested. This attack pattern, often associated with tools like Mimikatz, allows an adversary to pull password data from Active Directory. The rule excludes requests from known domain controller accounts.

Detects a sequence of events consistent with credential dumping of sensitive Windows registry hives (SAM, SYSTEM, SECURITY). The attack involves querying shadow copies using vssadmin, creating a symbolic link to the shadow copy volume via mklink, and copying the hive files from that location. Cleanup attempts using rmdir are also monitored.

Detects processes opening lsass.exe with high-risk access rights consistent with credential dumping (Sysmon EventID 10), including known dumping tool patterns such as procdump or rundll32 invoking the comsvcs.dll MiniDump export.

This rule detects unauthorized attempts to perform Active Directory replication requests (DCSync) by monitoring for specific Event IDs (4662), activity types (DsGetNCChanges, DRSUAPI), and known Directory Replication Service (DRS) UUIDs. It specifically flags requests originating from non-Domain Controller assets or workstations, which is a common indicator of credential dumping via tools like Mimikatz.

Detects DCSync activity, a method of credential dumping, by identifying DRSUAPI 'GetNCChanges' replication requests originating from a host that is not a recognized Domain Controller. The rule uses Active Directory replication GUIDs, explicit operation logs, and enriches host data to filter for illegitimate sources.
