Veeam, a popular backup and disaster recovery solution, stores credentials for backup operations in MSSQL databases. An attacker who gains access to these databases may attempt to use tools like \u003ccode\u003esqlcmd.exe\u003c/code\u003e or PowerShell commands (e.g., \u003ccode\u003eInvoke-Sqlcmd\u003c/code\u003e) to extract and decrypt these credentials. This tactic allows the attacker to compromise the backups themselves, preventing recovery and increasing pressure on the victim. This activity has been observed in real-world incidents, such as those involving the Diavol ransomware.
