The rule 'Veeam Backup Database Suspicious Query' is designed to detect potentially malicious activity targeting Veeam backup databases, particularly when unauthorized SQL queries are executed. It specifically looks for instances where the SQLCmd utility is used to perform suspicious queries from possibly compromised or unauthorized locations. By examining command lines that include specific keywords related to Veeam backup processes, it identifies attempts to extract sensitive operational information or credentials. This detection is crucial for security teams to mitigate the risk of data exfiltration and unauthorized access to backup resources.
