Correlates a successful Fortinet SSL VPN session with nltest, net, Get-AD*, AdFind, ldapsearch, WinRS, or WMIC discovery commands for the same account within forty-five minutes. This behavior can indicate an attacker establishing initial access via VPN and then performing internal reconnaissance.
Detects the execution of Windows Credential Editor (WCE), a post-exploitation tool used to extract plaintext passwords, hashes, PIN codes, and Kerberos tickets from memory. This tool is commonly employed by threat actors for credential dumping and facilitating lateral movement within compromised networks.

This query was originally published in the threat analytics report, Doppelpaymer: More human-operated ransomware. There is also a related blog.
DoppelPaymer is ransomware that is spread manually by human operators. These operators have exhibited extensive knowledge of system administration and common network security misconfigurations. For example, they use SysInternal utilities such as ProcDump to dump credentials from LSASS. They often use these stolen credentials to turn off security software, run malicious commands, and spread malware throughout an organization.
The following query detects ProcDump being used to dump credentials from LSASS.

This rule detects the creation of files with names commonly associated with credential dumping tools or files produced by them. It looks for specific filenames or patterns in the full path of newly created files, such as logs from fgdump, kirbi files, pwdump outputs, cachedump executables, procdump outputs, and Windows Credential Editor (WCE) related files. This indicates an attempt to extract credentials from the system.
This rule detects the execution of various Windows-based hacktools by matching their import hash (imphash). This method allows for detection even if the tool's filename has been changed. The rule includes imphashes for tools such as PetitPotam, JuicyPotato, RoguePotato, Pwdump, Cobalt Strike beacons, PPLDump, NanoDump, HandleKatz, DripLoader, UACMe, WCE, Sliver Stagers, Dumpert, SysmonEnte, SysmonQuiet, ShaprEvtMute Hook, Forkatz, PPLKiller, Backstab, Forensia, EDRSandBlast, and EDRSilencer.
This rule detects access to the 'wceaux.dll' file, which is associated with the Windows Credential Editor (WCE) tool. This activity is indicative of an attempt to perform pass-the-hash remote command execution, often used for credential dumping and lateral movement. The rule specifically looks for Security Event IDs 4656 (A handle to an object was requested) or 4663 (An attempt was made to access an object) where the accessed object's name ends with '\wceaux.dll'.
Detects wceaux.dll access while WCE pass-the-hash remote command execution on source host
This rule detects the execution of well-known credential dumping tools by monitoring Windows Security Event ID 4697, which signifies a service creation event. The rule specifically looks for service filenames containing keywords associated with common credential dumping utilities such as 'cachedump', 'dumpsvc', 'fgexec', 'gsecdump', 'mimidrv', 'pwdump', and 'servpw'. This indicates an adversary attempting to install and run a service that can extract credentials from the system.
This rule detects the execution of well-known credential dumping tools by monitoring Windows System event logs for Service Control Manager events (EventID 7045) indicating service creation. The rule specifically looks for service image paths containing keywords associated with common credential dumping utilities such as 'cachedump', 'dumpsvc', 'fgexec', 'gsecdump', 'mimidrv', 'pwdump', and 'servpw'. This helps identify attempts to install and run these tools as services for credential theft.
This rule detects the creation or modification of a specific registry key associated with Windows Credential Editor (WCE). WCE is a tool used to dump credentials from memory, specifically targeting the Local Security Authority Subsystem Service (LSASS). The rule looks for the string 'Services\WCESERVICE\Start' within the 'TargetObject' field of registry events, indicating the installation or activation of WCE as a service.
This rule detects the creation of files with names commonly associated with credential dumping tools or the output files generated by such tools. This includes executables of known credential dumpers like fgdump, pwdump, cachedump, procdump, and Windows Credential Editor (WCE), as well as output files like 'fgdump-log', 'kirbi', 'pwdump', 'pwhashes', 'wce_ccache', 'wce_krbtkts', 'NTDS.out', 'SAM.out', 'SECURITY.out', and 'SYSTEM.out'.
