Attack: Impair Defenses: Disable Cloud Logs
An adversary may disable or modify cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection. Cloud environments allow for collection and analysis of audit and application logs that provide insight into what activities a user does within the environment. If an adversary has sufficient permissions, they can disable or modify logging to avoid detection of their activities.
For example, in AWS an adversary may disable CloudWatch/CloudTrail integrations prior to conducting further malicious activity.(Citation: Following the CloudTrail: Generating strong AWS security signals with Sumo Logic) They may alternatively tamper with logging functionality – for example, by removing any associated SNS topics, disabling multi-region logging, or disabling settings that validate and/or encrypt log files.(Citation: AWS Update Trail)(Citation: Pacu Detection Disruption Module) In Office 365, an adversary may disable logging on mail collection activities for specific users by using the Set-MailboxAuditBypassAssociation cmdlet, by disabling M365 Advanced Auditing for the user, or by downgrading the user’s license from an Enterprise E5 to an Enterprise E3 license.(Citation: Dark Reading Microsoft 365 Attacks 2021)

Test : AWS - Disable CloudTrail Logging Through Event Selectors using Stratus
OS
- linux
- macos
- iaas:aws
Description:
Update event selectors in AWS CloudTrail to disable the logging of certain management events to evade defense. This Atomic test leverages a tool called Stratus-Red-Team built by DataDog (https://github.com/DataDog/stratus-red-team). Stratus Red Team is a self-contained binary. You can use it to easily detonate offensive attack techniques against a live cloud environment.
