It also makes it possible to detect accounts with an attack path to become a domain administrator, by relying on the data collected with Bloodhound. Mimikatz is arguably the most well-known/publicized way of dumping LSASS. Therefore, one way to detect if Empire has been injected into LSASS is to detect if the Microsoft .NET runtime has been loaded. Implement part of the NTLM protocol for the authentication with the hash and send commands over the network with protocols like SMB, WMI, etc. In addition, a debugger cannot be attached to LSASS when it is running as a protected process. The major difference between passing the hash to a legitimate NTLM connection is the use of a password. Microsoft recommends disabling WDigest authentication unless it is needed. Enable Protected Mode on LSASS. This is a list of several ways to dump LSASS.exe (Local Security Authority Subsystem Service). Mimikatz was created in 2007 by Benjamin Delpy as a tool to experiment with Windows security and LSASS functionality. APT32 : APT32 used Mimikatz and customized versions of Windows Credential Dumper to harvest credentials. Process dump. Pressing “Ctrl + D” will open the DLL viewer for a particular process. APT3 has used a tool to dump credentials by injecting itself into lsass.exe and triggering with the argument "dig." Windows. Note: Some AV may detect as malicious the use of procdump.exe to dump lsass.exe, this is because they are detecting the string "procdump.exe" and "lsass.exe". APT33 : APT33 has used a variety of publicly available tools like LaZagne, Mimikatz, and ProcDump to dump credentials. The default task manager has the functionality to perform a process dump. What makes this comscvs.dll technique convenient is that a dump can be created directly from the command line, without needing to click on GUI controls. So it is stealthier to pass as an argument the PID of lsass.exe to procdump instead o f the name lsass.exe. When it is enabled, Lsass.exe retains a copy of the user’s plaintext password in memory, where it can be at risk of theft. How to Activate Inject the hash to LSASS.exe and open session with the injected hash. Procdump can be used to dump lsass, since it is considered as legitimate thus it will not be considered as a malware.

Detect creation of dump files containing the memory space of lsass.exe, which contains sensitive credentials. Because of this, it’s possible to dump lsass memory on a host, download its dump locally and extract the credentials using Mimikatz.

Common credential dumpers such as Mimikatz access the LSA Subsystem Service (LSASS) process by opening the process, locating the LSA secrets key, and decrypting the sections in memory where credential details are stored. Credential dumpers may also use methods for reflective Process Injection to reduce potential … Conclusion LSASS is a process in Windows that is responsible for enforcing the security policy on the system. On Windows operating systems starting with 8.1, LSASS can be configured to run in “protected mode.” This means that only other protected-mode processes can call LSASS.
