Snapshots RDS públicos

AWS permite dar acceso a cualquiera para descargar snapshots RDS. Puedes listar estos snapshots RDS públicos muy fácilmente desde tu propia cuenta:

# Public RDS snapshots
aws rds describe-db-snapshots --include-public

## Search by account ID
aws rds describe-db-snapshots --include-public --query 'DBSnapshots[?contains(DBSnapshotIdentifier, `284546856933:`) == `true`]'
## To share a RDS snapshot with everybody the RDS DB cannot be encrypted (so the snapshot won't be encryted)
## To share a RDS encrypted snapshot you need to share the KMS key also with the account


# From the own account you can check if there is any public snapshot with:
aws rds describe-db-snapshots --snapshot-type public [--region us-west-2]
## Even if in the console appear as there are public snapshot it might be public
## snapshots from other accounts used by the current account
