Detection of compromised ( LinkById: T1078) in-use by adversaries may help as well. Others will make an in-memory copy of the SAM table before reading hashes. Some hash dumpers will open the local file system as a device and parse to the SAM table to avoid file access defenses. Monitor for hash dumpers opening the Security Accounts Manager (SAM) on the local file system ( %SystemRoot%/system32/config/SAM). PowerShell scripts also exist that contain credential dumping functionality, such as PowerSploit's Invoke-Mimikatz module, which may require additional logging features to be configured in the operating system to collect necessary information for analysis. Remote access tools may contain built-in features or incorporate existing tools like Mimikatz. Look for command-lines that invoke AuditD or the Security Accounts Manager (SAM). Monitor executed commands and arguments that may attempt to dump credentials to obtain account login and credential material, normally in the form of a hash or a clear text password, from the operating system and software. Monitor for replication requests from IPs not associated with known domain controllers. ![]() Note: Domain controllers may not log replication requests originating from the default domain controller account. Monitor domain controller logs for replication requests and other unscheduled activity possibly associated with DCSync. #Tiworker.exe windows 10 process monitor password#Limit credential overlap across accounts and systems by training users and administrators not to use the same password for multiple accounts. ![]() #Tiworker.exe windows 10 process monitor windows 8.1#On Windows 8.1 and Windows Server 2012 R2, enable Protected Process Light for LSA. Follow best practices in restricting access to privileged accounts to avoid hostile programs from accessing such sensitive regions of memory. Linux:Scraping the passwords from memory requires root privileges. Follow best practices for design and administration of an enterprise network to limit privileged account use across administrative tiers. Windows:Do not put user or admin domain accounts in the local administrator groups across systems unless they are tightly controlled, as this is often equivalent to having a local administrator account with the same password on all systems. Įnsure that local administrator accounts have complex, unique passwords across all systems on the network. Consider disabling WDigest authentication. Įnsure Domain Controller backups are properly secured.Ĭonsider disabling or restricting NTLM. It also does not protect against all forms of credential dumping. It is not configured by default and has hardware and firmware system requirements. With Windows 10, Microsoft implemented new protections called Credential Guard to protect the LSA secrets that can be used to obtain credentials through forms of credential dumping. On Windows 10, enable Attack Surface Reduction (ASR) rules to secure LSASS and prevent credential stealing. This can help limit the caching of users' plaintext credentials. Consider adding users to the "Protected Users" Active Directory security group. Manage the access control list for "Replicating Directory Changes" and other permissions associated with domain controller replication. Trojan.Karagany can dump passwords and save them into \ProgramData\Mail\MailAg\pwds.txt. Tonto Team has used a variety of credential dumping tools. Suckfly used a signed credential-dumping tool to obtain victim account credentials. Sowbug has used credential dumping tools. Revenge RAT has a plugin for credential harvesting. Poseidon Group conducts credential dumping on victims, with a focus on obtaining credentials belonging to domain and database servers. Credentials targeted by PinchDuke include ones associated many sources such as WinInet Credential Cache, and Lightweight Directory Access Protocol (LDAP). #Tiworker.exe windows 10 process monitor code#PinchDuke's credential stealing functionality is believed to be based on the source code of the Pinch credential stealing malware (also known as LdPinch). PinchDuke steals credentials from compromised hosts. OnionDuke steals credentials from its victims. Leviathan has used publicly available tools to dump password hashes, including HOMEFRY. įrankenstein has harvested credentials from the victim's machine using Empire. Ĭarbanak obtains Windows logon password details. Īxiom has been known to dump credentials. ĪPT39 has used different versions of Mimikatz to obtain credentials. ĪPT32 used GetPassword_圆4 to harvest credentials. APT28 regularly deploys both publicly available (ex: Mimikatz) and custom password retrieval tools on victims. ![]()
