Data Destruction: Lifecycle-Triggered Deletion
5 rules across 2 sources.
From MITRE ATT&CK 19.2
Adversaries may modify the lifecycle policies of a cloud storage bucket to destroy all objects stored within.
Cloud storage buckets often allow users to set lifecycle policies to automate the migration, archival, or deletion of objects after a set period of time. If a threat actor has sufficient permissions to modify these policies, they may be able to delete all objects at once.
For example, in AWS environments, an adversary with the PutLifecycleConfiguration permission may use the PutBucketLifecycle API call to apply a lifecycle policy to an S3 bucket that deletes all objects in the bucket after one day. In addition to destroying data for purposes of extortion and Financial Theft, adversaries may also perform this action on buckets storing cloud logs for Indicator Removal.

How MITRE says to detect it DET0041
Detection of Lifecycle Policy Modifications for Triggered Deletion in IaaS Cloud Storage
IaaS Analytic 0117
Adversary with write access to storage modifies lifecycle policies (e.g., via PutBucketLifecycle) to schedule rapid object deletion across one or more storage buckets. This is often used to trigger impact (destruction), remove logs (defense evasion), or force extortion (ransomware).
