If we have very good connectivity and the dump is not too big, it is possible to download the dump before it’s being deleted.

When the dumping process is finished, Windows Defender removes the dump after a few seconds. Although procdump is a trusted tool from Windows perspective, dumping lsass is considered as suspicious activity by Windows Defender. Windows DefenderĪ second limitation due to Windows Defender was encountered. All the steps presented in the previous section are applicable, and when lsass dump has been downloaded to the attacker’s host, pypykatz is used to extract usernames and passwords or NT hashes from this dump.

Thanks to this project, it is now possible to do everything from a Linux machine.

It attaches to the process, reads its memory and write it into a file. The procdump tool is one of these tools, and its job is to dump a running process memory. This toolset has been adopted by a large number of administrators and developers, so Microsoft decided to buy it in 2006, and the executables are now signed by Microsoft, therefore considered legitimate by Windows.

Procdump is a tool from the Sysinternals suite which was written by Marc Russinovich to helps sysadmins.

Manual method : Procdumpīecause of this, I used to do this manually with the tool called Procdump. Thus, if a privileged account is connected to one of the compromised hosts, the Mimikatz module allows you to quickly extract its credentials and thus take advantage of the privileges of this account to compromise more resources.īut today, the majority of antivirus detects the presence and/or execution of Mimikatz and blocks it so CrackMapExec module is just hanging, waiting for a response from the server, but it never gets it because the process was killed. This is why Mimikatz extracts the information located in these different SSPs in an attempt to find some authentication secrets, and displays them to the attacker. For practical reasons, the credentials entered by a user are very often saved in one of these SSPs so that the user doesn’t have to enter them again a few seconds or minutes later. lsass contains all the Security Service Providers or SSP, which are the packets managing the different types of authentication. CrackMapExec runs Mimikatz on remote machines to extract credentials from lsass memory or Local Security Authority SubSystem. There is one in particular, which was very effective for some time, it was the module Mimikatz. There are already a lot of them, such as the enumeration of different information (DNS, Chrome credentials, installed antivirus), the execution of BloodHound ingestor or a module that looks for credentials in “Group Policy Preferences”. It is possible to create its own modules that the tool will execute when it logs in to the machine.

The tool allows you to authenticate on remote machines with a domain or local account, and a password or a LM-NT hash.ĬrackMapExec was developed in a modular way. Its purpose is to asynchronously be able to execute actions on a set of machines. The CrackMapExec tool is developed and maintained by Byt3bl33d3r. There are a multitude of ways to do one or the other, but today we will present a new technique for reading the content of a lsass dump remotely, significantly reducing latency and detection during password extraction on a set of machines.Ī small introductory message to thank mpgn who helped me a lot on different subjects, and with whom I worked on this project, and Skelsec for his advice and ideas. In corporate penetration tests, lateral movement and elevation of privilege are two fundamental concepts for advancing and gaining control of the target.
