PSA: If you use #Veeam Backup & Replication (very common), upgrade. Especially if you face server to internet.

Screenshot from Code White, the API lets you remotely request Windows admin credentials for some reason, no auth request.

In their advisory Veeam claimed these are encrypted... it's base64 (lololol)

Try to be lazy and don’t expose it right from the start
