Detects an inbound public network or remote interactive logon to a device, followed within 24 hours by credential-dumping activity, and subsequently within 7 days by email data staging (creation or modification of PST, OST, EML, or MBOX files) on the same device.
Detects PaperCut server processes (such as pc-app.exe, pc-server.exe, or Java running PaperCut) spawning command shells or utility binaries associated with credential dumping, internal reconnaissance, or pivoting.
Detects unauthorized access to virtual hard disk (VMDK) files by non-standard processes followed by the creation or modification of sensitive offline credential artifacts such as ntds.dit or SYSTEM hives on the same host within a 2-hour window, indicating potential offline credential theft.
The following analytic detects the creation of an lsass.exe process dump using Windows Task Manager.
It leverages Sysmon EventID 11 to identify file creation events where the target filename matches *lsass*.dmp.
This activity is significant because creating an lsass dump can be a precursor to credential theft, as the dump file contains sensitive information such as user passwords.

This activity is significant because creating an lsass dump can be a precursor to credential theft, as the dump file contains sensitive information such as user passwords.
The following analytic detects a suspicious registry modification that enables the plain text credential feature in Windows by setting the "UseLogonCredential" value to 1 in the WDigest registry path. This detection leverages data from the Endpoint.Registry data model, focusing on specific registry paths and values. This activity is significant because it is commonly used by malware and tools like Mimikatz to dump plain text credentials, indicating a potential credential dumping attempt. If confirmed malicious, this could allow an attacker to obtain sensitive credentials, leading to further compromise and lateral movement within the network.
The following analytic detects the use of procdump.exe to dump the LSASS
process, specifically looking for the -mm and -ma command-line arguments. It leverages
data from Endpoint Detection and Response (EDR) agents, focusing on process names,
command-line executions, and parent processes. This activity is significant because
dumping LSASS can expose sensitive credentials, posing a severe security risk. If
confirmed malicious, an attacker could obtain credentials, escalate privileges,
and move laterally within the network, leading to potential data breaches and further
compromise of the environment.

The following analytic detects the execution of tools commonly exploited by cybercriminals, such as those used for unauthorized access, network scanning, privilege escalation, password dumping or data exfiltration.
It leverages process activity data from Endpoint Detection and Response (EDR) agents, focusing on known attacker tool names.
This activity is significant because it serves as an early warning system for potential security incidents, enabling prompt response. If confirmed malicious, this activity could lead to unauthorized access, data theft, or further network compromise, posing a severe threat to the organization's security infrastructure.

Detects attempts to dump the Local Security Authority Subsystem Service (LSASS) process memory for credential harvesting. The rule monitors for unauthorized process access requests (e.g., PROCESS_VM_READ), suspicious file creation of memory dumps in common writeable directories, and command-line execution of tools or techniques commonly associated with LSASS dumping (e.g., Mimikatz, procdump, or abusing comsvcs.dll).
This rule detects unauthorized attempts to dump the memory of the Local Security Authority Subsystem Service (LSASS) process. It monitors for common post-exploitation tools (such as procdump, mimikatz, nanodump, and sqldumper) or built-in Windows techniques (using rundll32.exe with comsvcs.dll) that are typically used to extract sensitive credential material from process memory.
Detects a suspicious command-line chain where 'cmdkey' is used to add credentials, followed by the execution of 'regsvr32' targeting a DLL file hosted on a remote UNC path. This pattern is commonly associated with ClickFix or FileFix techniques where an adversary attempts to force authentication and execute malicious code via proxy execution.
Detects unauthorized processes attempting to open handles to the Local Security Authority Subsystem Service (LSASS) process with access rights consistent with credential dumping (e.g., PROCESS_VM_READ, PROCESS_ALL_ACCESS). This rule also specifically flags the use of well-known tools and techniques such as Mimikatz, ProcDump, and the abuse of rundll32.exe with comsvcs.dll for memory extraction, which is indicative of OS Credential Dumping (T1003.001).
This rule detects artifacts and command-line patterns associated with Impacket utility suite modules, specifically wmiexec.py, smbexec.py, and secretsdump.py. These tools are commonly used by adversaries for remote command execution, lateral movement, and dumping of sensitive domain or system credentials.
Detects credential-dumping modules (such as nanodump, hashdump, and lsadump variants) associated with AdaptixC2 framework being invoked or used by the 'mscopilot.exe' process. The rule monitors for command-line arguments indicating credential extraction, unauthorized attempts to open handle to lsass.exe, and access to sensitive registry hives (SAM, Security, LSA) by the suspect process.
Detects the use of ntdsutil.exe with arguments indicative of Install From Media (IFM) backup creation, correlated with subsequent access to the ntds.dit file on the same device within a one-hour window. This behavior is commonly associated with attackers attempting to harvest the Active Directory database for offline credential cracking.
Detects attempts to dump credentials from the Local Security Authority Subsystem Service (LSASS) process memory using common tools like Mimikatz, Procdump, or built-in system utilities such as comsvcs.dll or command-line arguments indicating memory dump operations.
Detects suspicious post-compromise activity associated with ALPHV/BlackCat affiliates. This rule monitors for anomalous Kerberos ticket requests (e.g., weak encryption types or TGS requests) closely followed by access to sensitive credential stores or tools on the same host, which is indicative of credential harvesting after a session hijacking or initial access event.
Detects a process initiating a memory dump of lsass.exe (using --dump arguments) followed within 15 minutes by the creation of a hexadecimal-named .tmp file in the Windows\Temp directory. This behavioral pattern is characteristic of credential dumping using reflected cloning or similar techniques, followed by the staging of obfuscated or encrypted minidump data for exfiltration.
Detects attempts to create a memory dump of the Local Security Authority Subsystem Service (LSASS) process using well-known utilities such as procdump, rundll32 with comsvcs.dll, and taskmgr, which are frequently used by adversaries to perform credential dumping.
Detects the presence of an unpacked Sauron Loader DLL by identifying a specific embedded configuration header (magic value 0xbaadf00d followed by flags 0x40) in conjunction with configuration fields like 'group_id' or 'build_id'. This rule is intended for static analysis of file samples.
Detects a suspicious pattern where a single process loads high-risk cryptography and system-level modules (e.g., sqlite3, win32crypt, win32api) followed within 30 minutes by credential harvesting actions such as dumping Wi-Fi keys using 'netsh' or establishing persistence via 'schtasks'. This behavior is indicative of a 'lazy-import' stealer or malicious loader attempting to evade simple signature-based detection.
Detects instances where a process attempts to access the memory of the Local Security Authority Subsystem Service (LSASS.exe) with suspicious access rights often associated with credential dumping. The rule excludes known benign processes such as antivirus and debugging tools.
