AWS CloudShell Environment Created

Description

Identifies the creation of a new AWS CloudShell environment. CloudShell is a browser-based shell that provides command-line access to AWS resources directly from the AWS Management Console. The CreateEnvironment API is called when a user launches CloudShell for the first time or when accessing CloudShell in a new AWS region. Adversaries with console access may use CloudShell to execute commands, install tools, or interact with AWS services without needing local CLI credentials. Monitoring environment creation helps detect unauthorized CloudShell usage from compromised console sessions.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Known benign triggers

Legitimate use of CloudShell by administrators for routine AWS management tasks. Verify whether the user has a legitimate need for CloudShell access and correlate with recent console login activity. Environment creation also occurs when users access CloudShell in a new AWS region.
