AWS blocks compromised IAM keys with automatic policy

AWS has implemented the managed policy AWSCompromisedKeyQuarantine to mitigate risks related to publicly exposed IAM access keys, an initial attack vector for most incidents on cloud environments. The policy was created on August 11, 2020, with significant updates in versions 2 (April 21, 2021) and 3 (August 21, 2024).

Quick Response

The AWSCompromisedKeyQuarantine policy automatically blocks access to certain actions when IAM credentials are compromised. It is applied in three phases: email notification, policy activation, and opening a support ticket. The current policy (version 3) was released on August 8, 2024.

Security Policy Evolution

IAM access keys, if not compliant with the principle of least privilege, represent a significant risk for organizations. When AWS detects exposed credentials in public GitHub repositories or through other notifications, it automatically activates a protection process. This mechanism was first documented by cloud security scholar Pawel Rzepa in 2019.

Activation Mechanism

The process of activating the AWSCompromisedKeyQuarantine policy has undergone several revisions. Initially, AWS simply notified the account owner via email. Subsequently, it introduced automatic activation of the policy on the associated IAM user. The current version also includes opening a support ticket to guide the user through the remediation process.

Integration with GitHub

Since 2020, AWS has collaborated with GitHub's secret scanning program to identify and protect exposed credentials. The scanning program, launched in 2018, uses specific sequences to detect exposed credentials in public repositories and npm packages. This mechanism was enhanced with validity checks introduced in January 2023 and push protection added in August 2023.

Monitoring and Incident Response

To ensure a rapid response to incidents, security teams must implement effective monitoring strategies. AWS provides tools to detect quarantine events in its logging environments. This proactive approach allows for timely limitation of potential damage caused by fraudulent activities.
