What it detects

This rule detects PowerShell activity that extracts and decrypts stored credentials from a Veeam backup server database. Abyss Locker operators ran an obfuscated variant of a public Veeam credential dumping script to recover accounts for lateral movement before deploying ransomware. Legitimate use of such scripts against production backup servers is uncommon.
