Major AI LLM Breach Exposes Critical Cybersecurity Flaws

Executive Summary

In October 2024, a major breach impacting cloud-hosted large language models (LLMs) was reported by Permiso Security, uncovering significant cybersecurity vulnerabilities across platforms such as AWS Bedrock, Anthropic, and Google Vertex AI. This incident, termed “LLMjacking,” exploited flaws in the cloud infrastructure of AI applications, allowing attackers to gain unauthorized access through compromised cloud access keys. These keys were likely obtained via phishing schemes or inherent framework vulnerabilities. By leveraging these credentials, the attackers bypassed conventional security measures, executing API calls that enabled them to hijack AI resources. The breach highlights the urgent need for enhanced security protocols in cloud-based AI systems to protect sensitive data and maintain operational integrity.
