Top Open Source Tools for Red Teams

No matter how much protection you have provided to your data, systems, and networks, there is always a vulnerability that leads a hacker into your organization and lets him/her access your sensitive information. So, to know those vulnerabilities, organizations hire red team members to think and act exactly like hackers, but with a good intention. 

Top Open Source Tools for Red Teams

Red team members follow a procedure to learn about vulnerabilities and exploit them; this procedure is divided into steps, and the red team members use different tools in each step. So in this blog, let’s see some of the very important tools that red team members use in every phase.

Tools for Red Team

Reconnaissance: Reconnaissance is one of the most popular and important steps in any red team assessment. At this stage, the red team gathers all the information about the target system or network. There are three popular reconnaissance tools; they are:

Nmap: Nmap is a commonly used and excellent tool for reconnaissance. Along with being a network scanner, it offers a wide range of useful features. The Red Team can learn a great deal about any computer that can be reached over the network using Nmap. The use of network scanning, however, must be handled carefully because it can easily be detected.

Censys: Censys provides a way to collect data on all of your assets in order to assist you in preventing target assaults. This application gives actionable data and assists you in tracking changes in all of your assets and identifying possible weaknesses.

Shodan: Shodan is a kind of search engine for devices that are connected to the internet. With IoT devices being widely deployed and their poor security, they can serve as an excellent entry point for a Red Team. Shodan can assist with discovering and classifying these devices.

Gaining and maintaining access: Once the red team has gathered all the information about the target, the next immediate thing they will have to do is try to exploit the vulnerabilities and gain access to the organization’s systems and networks. And then they have to maintain that access, so here are the tools that help red teams gain and maintain access.

Ncat: Information security experts call NCAT the Swiss Army knife of security. The fundamental function of this program is to establish a connection with any port using TCP/UDP. It can be used to scan port numbers, grab banners, grab data, create a remote shell, and many other things.

SET: A Social Engineering Toolkit (SET) allows you to build phishing attacks and test your customers’ resilience against social engineering. Phishing emails, websites, and malicious attachments can be created with this tool.

Metasploit: Though Metasploit is primarily a commercial tool, its community edition is still very powerful. The Metasploit Framework is considered the world’s top exploitation framework, offering over 1,500 in-built exploits and the capability of integrating custom ones.

Network analysis: By gaining access to the customer’s internal network, the Red Team can provide a wealth of information. In addition to passive network reconnaissance, active network reconnaissance can uncover the network infrastructure, services running and being used by various machines, and even user credentials if insecure protocols are being used. The tools used for network analysis are.

Aircrack-ng: Aircrack-ng is a tool that comes with Kali Linux and is used to hack wifi networks. This tool combines a packet sniffer, a WEP and WPA/WPA2 cracker, a network analysis tool, and a hash capturing tool into one application. The tool can be used to hack into wifi networks.

Wireshark: Network protocol analyzers such as Wireshark capture packets from network connections, such as those connecting your computer to the internet or to your home office. Data packets make up the discrete units of data in an Ethernet network. The most popular packet sniffer in the entire world is Wireshark.

Reporting: After completing the entire process, such as gathering the information, exploiting vulnerabilities, and maintaining access, the red teams have to prepare a report of all the open ports and vulnerabilities of the organizations. After receiving this report, the company’s defensive team works on their weak points. Here are the tools used by red teams for reporting.

Dardis: Information security professionals use Dardis for reporting and collaboration. It allows the Red Team to quickly generate reports and track their activities throughout the assessment process with just a single click. Additionally, it can be integrated directly with tools such as Nmap and Nessus. 

MITRE ATT&CK: As part of MITRE ATT&CK, the cyberattack life cycle is broken down into parts and describes various methods to achieve each stage. In fact, it is helpful for both the planning stages of the assessment because it ensures the red team does not always use the same methods of attack, and it provides additional context to the customer about vulnerabilities.
