Hi,
Wazuh can help detect phishing emails by correlating email-related events with threat intelligence. To do this, you first need to forward email logs from your mail platform to the Wazuh Manager for analysis.
Wazuh supports multiple log ingestion methods. You can choose the one that best fits what your mail platform supports:
1. Sending logs via syslogThe Wazuh Manager has a built-in syslog listener. If your mail platform supports syslog forwarding, you can send the logs directly to the Wazuh Manager using this method. You can refer to the Wazuh documentation for configuring the Manager to receive syslog events.
2. Monitoring logs from a fileIf the email logs are stored in a log file on a server, you can install a Wazuh agent on that server and configure localfile monitoring. This allows Wazuh to monitor the log file in real time and forward the events to the Manager for analysis. Refer to the Wazuh documentation for installing the agent and configuring local file monitoring.
3. Forwarding logs using the Wazuh Manager APIYou can also send logs to the Wazuh Manager using its API. This approach is useful when logs are available programmatically rather than through syslog or files. The Wazuh documentation provides details on how to ingest logs using the Manager API.
Once the logs are ingested into the Wazuh Manager, you can create custom decoders and rules to analyze the events and trigger alerts.
To determine whether an email is phishing, you can enrich the events using threat intelligence sources such as VirusTotal or similar platforms. For example, URLs or domains extracted from email events can be checked against threat intelligence feeds. If a match is found, Wazuh can generate an alert indicating a potential phishing email.
