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.

This rule detects potentially malicious activities aimed at credential harvesting and system recovery inhibition. It monitors for the execution of vssadmin.exe with arguments to list shadow copies (often a precursor to deletion) or references to DPAPI master keys in command lines. Additionally, it identifies unauthorized processes attempting to access sensitive browser-based credential files (e.g., Login Data, Cookies, key4.db) from standard browser installation paths, specifically excluding legitimate browser and update processes.

Adversaries may directly access a volume to bypass file access controls and file system monitoring. Windows allows programs to have direct access to logical volumes. Programs with direct access may read and write files directly from the drive by analyzing file system data structures. This technique may bypass Windows file access controls as well as file system monitoring tools. (Citation: Hakobyan 2009)
Utilities, such as NinjaCopy, exist to perform these actions in PowerShell.(Citation: Github PowerSploit Ninjacopy) Adversaries may also use built-in or third-party utilities (such as vssadmin, wbadmin, and esentutl) to create shadow copies or backups of data from system volumes.(Citation: LOLBAS Esentutl)
I utilized Atomic Red Team to generate the telemetry and created these three queries to capture this activity.

This rule detects HTTP requests attempting to perform Local File Inclusion (LFI) or path traversal attacks by searching for patterns such as '/../' sequences and common sensitive file paths like /etc/passwd, /etc/shadow, or /proc/self/environ in the URI.
Detects attempts to access or exfiltrate the Windows Security Account Manager (SAM) or SYSTEM registry hives, which are primary targets for extracting credential hashes. This rule identifies common attack vectors including native Windows registry utilities (reg.exe), PowerShell-based volume shadow copy techniques (Invoke-NinjaCopy), and known credential dumping tools like secretsdump (from the Impacket suite) executed via command line or interpreted through Python.
This rule detects suspicious SMB traffic targeting raw disk volumes (e.g., PhysicalDrive, C:) or sensitive Windows files such as NTDS.dit and SYSTEM hive files. This behavior is indicative of credential dumping attempts, often performed using tools like secretsdump.py or Invoke-NinjaCopy, which bypass standard file system access controls to exfiltrate critical system credentials.
Detects the use of native Windows utilities (vssadmin, ntdsutil, diskshadow, esentutl) or command-line execution (cmd, powershell) to access, copy, or create shadow copies of the Active Directory database file (NTDS.dit), which is a common indicator of credential dumping.
Detects various techniques used to extract the Active Directory NTDS.dit database on Windows. The rule monitors for the misuse of administrative tools including ntdsutil.exe (for IFM or instance activation), vssadmin.exe (to create volume shadow copies as a prerequisite), and esentutl.exe (for direct ESE database operations). The detection focuses on suspicious command-line patterns indicative of credential dumping attempts.
Detects potential credential dumping activities and unauthorized access to sensitive system files. The rule monitors for three primary indicators: raw disk device access (often associated with volume shadow copy dumping), suspicious DiskShadow utility execution, and NTDS.dit extraction using ntdsutil. Known administrative and backup software processes are excluded to minimize noise.
This rule monitors for the execution of native Windows utilities (vssadmin.exe, ntdsutil.exe, diskshadow.exe, esentutl.exe) commonly abused by attackers to create volume shadow copies or access the NTDS.dit file for credential dumping or system recovery inhibition.

Known administrative and backup software processes are excluded to minimize noise.
Detects the unauthorized access or copying of the Active Directory NTDS.dit database file, a common credential harvesting technique. The rule monitors for the execution of ntdsutil.exe or vssadmin.exe with arguments typically used to create shadow copies or extract the NTDS database, specifically when executed by cmd.exe or powershell.exe.
Detects unauthorized attempts to extract the Active Directory database (NTDS.dit) for credential harvesting. The rule monitors for common administrative tools like ntdsutil.exe and vssadmin.exe being used to create shadow copies or extract the NTDS database, as well as direct file manipulation of ntds.dit. This activity is often associated with post-exploitation credential dumping techniques.
Detects the execution of built-in Windows utilities such as ntdsutil.exe, vssadmin.exe, and diskshadow.exe, often used by attackers to dump the Active Directory database (NTDS.dit) or manipulate volume shadow copies for credential theft or data staging/destruction purposes.
