What it detects

This rule detects deletion of S3 buckets through the DeleteBucket API, a destructive action the Bling Libra group behind ShinyHunters took after stealing data to pressure victims during extortion. Removing buckets destroys data availability and leaves a ransom note in a newly created bucket. Detecting this exposes destructive impact on cloud storage during an extortion event.
