CrackMapExec: A Swiss Army Knife for Pentesting Networks
CrackMapExec (CME) is a tool that allows you to perform various tasks on Windows networks, such as enumeration, credential dumping, lateral movement, command execution and more. It is inspired by tools like CredCrack, smbexec and smbmap, and uses the Impacket library to interact with various protocols such as SMB, WMI, MSSQL and LDAP.
CME can be installed in different ways, depending on your preference and needs. You can use Docker to pull the latest image from byt3bl33d3r/crackmapexec, or you can download the official binary releases from the GitHub page. Alternatively, you can use pipx to install CME as a Python package, or you can clone the source code from GitHub and use Poetry to manage the dependencies.
Once you have CME installed, you can use it to scan your target network for hosts, shares, users, groups and other information. You can also use it to dump hashes or tickets from remote machines, or to execute commands or scripts on them. CME supports various modules and plugins that extend its functionality and allow you to perform more advanced attacks. For example, you can use the mimikatz module to inject Mimikatz into memory and dump credentials, or you can use the empire module to launch Empire agents on remote hosts.
CME is a powerful and versatile tool that can help you in your pentesting engagements. It is constantly updated and improved by its developers and contributors. You can find more documentation and usage examples on the project's wiki or on the official Discord channel.One of the most useful features of CME is its ability to perform pass-the-hash and pass-the-ticket attacks. This means that you can use the hashes or tickets that you dump from one machine to authenticate to another machine without cracking them. This can help you to escalate your privileges and move laterally across the network. CME can also perform Kerberoasting and AS-REP Roasting attacks, which allow you to request and crack service tickets from the domain controller.
CME also has a stealth mode that enables you to perform your tasks without generating too much noise or triggering alerts. For example, you can use the wmiexec module to execute commands via WMI without creating a new process on the target machine, or you can use the atexec module to execute commands via the Task Scheduler without leaving any traces on disk. You can also use the --server option to run CME as a server and receive connections from remote hosts via SMB or HTTP.
CME is not only a tool for Windows networks, but also for Linux and macOS networks. You can use the ssh module to connect to SSH servers and execute commands or upload files, or you can use the smb module to connect to SMB servers and enumerate shares or files. You can also use the rdp module to connect to RDP servers and take screenshots or launch GUI applications.CME can also work well with other tools that can enhance your pentesting workflow. For example, you can use Nmap to scan your target network and feed the results to CME using the --nmap option, or you can use BloodHound to analyze the network topology and find the shortest path to domain admin using the --bloodhound option. You can also use CME to launch other tools on remote hosts, such as PowerSploit, Responder, or Mimipenguin.
However, CME is not a magic bullet that can solve all your pentesting problems. It still has some limitations and challenges that you need to be aware of and overcome. For example, CME may not work well on networks that have strict firewall rules or network segmentation, or on hosts that have antivirus or endpoint protection software installed. You may also encounter bugs or errors while using CME, or you may find some features missing or incomplete.
If you encounter any issues while using CME, you can report them on the GitHub page or on the Discord channel. You can also request new features or improvements that you would like to see in CME. The developers and contributors of CME are always open to feedback and suggestions from the users. You can also contribute to CME development by submitting pull requests or donating to the project. 06063cd7f5
