A recent LLMjacking attack has been documented, where threat actors exploited a leaked AWS IAM access key with AdministratorAccess permissions to hijack access to premium AI models, specifically targeting Amazon Bedrock. Security researchers at FortiGuard Labs traced the incident back to a long-lived AWS Identity and Access Management (IAM) access key. This attack method allows attackers to generate new identities and run inference on costly generative AI services, creating a significant revenue stream for the attackers. The incident highlights the vulnerabilities associated with cloud credential management and the potential financial impact on organizations relying on these AI services. As of now, the attack method has been confirmed and is a growing concern in the cybersecurity landscape.
