The 'OpenCanary - MySQL Login Attempt' rule is designed to detect unauthorized login attempts against a MySQL service running on an OpenCanary node. This rule utilizes logs generated by the OpenCanary application, specifically monitoring for logs of a certain type (logtype 8001) that correspond to login attempts. This detection is crucial for identifying potential credential access or brute-force attacks targeting MySQL databases within a simulated environment. Given that OpenCanary emulates various services to attract and record malicious activity, effectively monitoring the MySQL service helps improve the overall security posture by recognizing attempted unauthorized access. The rule has been classified with a high severity level due to the potential impact of successful logins, which can lead to further exploitation of the database and the underlying system.
