Threat Crowd

Overview :

ThreatCrowd is a free online platform that provides a search engine and information repository for cybersecurity threats. It collects and aggregates information on various threats such as malware, domains, IP addresses, email addresses, and other indicators of compromise (IOCs).

The platform uses various sources to gather and analyze this information, including public and private feeds, user submissions, and other sources. ThreatCrowd provides users with a central location to search for information on potential threats, and it can be used to identify and investigate suspicious activity, as well as to monitor and track threats over time.

The benefits of ThreatCrowd include:

• Centralized information: ThreatCrowd provides a centralized location to search for information on cybersecurity threats, making it easier for users to investigate and analyze potential threats.

•Comprehensive data: ThreatCrowd aggregates information from a variety of sources, including public and private feeds, user submissions, and other sources, providing users with a more comprehensive view of potential threats.

• Quick identification: ThreatCrowd allows users to quickly identify and investigate potential threats, providing them with valuable information to take action to prevent or mitigate an attack.

• Historical data: ThreatCrowd keeps a historical record of all identified threats, allowing users to track the evolution of specific threats over time and identify patterns or trends.

• Cost-effective: ThreatCrowd is a free platform, making it an affordable option for organizations and individuals looking to improve their cybersecurity posture without incurring additional costs.

Integrating ThreatCrowd with Wazuh can provide several benefits:

•Improved threat detection: By integrating ThreatCrowd with Wazuh, users can enhance their threat detection capabilities. Wazuh can use ThreatCrowd’s threat intelligence to identify and alert users to potential threats that may have been missed otherwise.

• Centralized management: Integrating ThreatCrowd with Wazuh provides a central location for managing threat intelligence. This can streamline the process of identifying and responding to threats and reduce the time and effort required to investigate potential threats.

• Increased efficiency: By automating the process of gathering threat intelligence, users can save time and improve their efficiency. Wazuh can automatically pull threat intelligence from ThreatCrowd, allowing users to focus on other important tasks.

• More comprehensive view of threats: Integrating ThreatCrowd with Wazuh can provide users with a more comprehensive view of potential threats. Wazuh can combine ThreatCrowd’s threat intelligence with other sources of data to provide a more complete picture of potential threats.

• Better decision-making: By providing more accurate and timely threat intelligence, integrating ThreatCrowd with Wazuh can help users make better-informed decisions about how to respond to potential threats. This can improve their overall security posture and reduce the risk of a successful cyber-attack.

Steps for integrating ThreatCrowd with Wazuh:

•Obtain an API key from ThreatCrowd: First, you need to register for a free account on the ThreatCrowd website to obtain an API key.

• Install the ThreatCrowd API script: Next, you need to install the ThreatCrowd API script on your Wazuh server. You can do this by using the following commands on the command line:

 
     >>>[cd /var/ossec/integrations/threatcrowd
     sudo curl -O https://raw.githubusercontent.com/wazuh/wazuh/4.2/extensions/threat-intel/threatcrowd/threatcrowd.py ]
                sudo chmod +x threatcrowd.py

Configure the ThreatCrowd API script: Once the script is installed, you need to configure it to use your ThreatCrowd API key. You can do this by editing the “threatcrowd.py” file and adding your API key to the “API_KEY” variable.

>>> [API_KEY = 'your-api-key-here']

Configure the Wazuh API: Now, you need to configure the Wazuh API to use the ThreatCrowd API script. You can do this by adding a new configuration block to the “api.config” file. Open the file with a text editor, add the following configuration block at the end, and save the file.

>>[
       <api>
       <name>threatcrowd</name>
              <url>/usr/bin/python3 /var/ossec/integrations/threatcrowd/threatcrowd.py -q %QUERY</url>
       </api>
   ]

Test the integration: To test the integration, you can run a search in Wazuh for a known threat. For example, you can search for an IP address using the following command:

 [sudo /var/ossec/api/configuration/search.py -a threatcrowd -q <ip_address>]

Fine-tune the integration: Finally, you can fine-tune the integration to adjust the search parameters and filter out irrelevant data. You can modify the ThreatCrowd API script to change the search parameters, such as the search type or the result limit.

Conclusion :

Integrating ThreatCrowd with Wazuh is a straightforward process that involves obtaining an API key, installing the ThreatCrowd API script on your Wazuh server, configuring the script and the Wazuh API, and testing and fine-tuning the integration as needed. With this integration in place, you can take advantage of the rich threat intelligence data provided by ThreatCrowd and improve your organization’s security posture.
