Summary
This detection rule identifies when object versioning is suspended for an Amazon S3 bucket, which is a critical feature that allows for multiple versions of an object to be stored. Suspending versioning may indicate malicious intent, as it prevents recovery of objects that may be deleted or overwritten. The rule employs EQL (Event Query Language) to detect the `PutBucketVersioning` API call that specifically sets the versioning status to `Suspended`. The potential risk associated with this action includes adversaries disarming the recovery mechanisms of an S3 bucket, making it easier to delete or alter data without the possibility of reverting to previous versions. This can be crucial in ransomware scenarios and other attack vectors aimed at impeding data recovery efforts.
