Serverless Tokens in the Cloud: Exploitation and Detections

SUMMARY :

This article explores the security implications of serverless authentication across major cloud platforms. It details how attackers target serverless functions to exploit vulnerabilities arising from insecure code and misconfigurations. The mechanics of serverless authentication are explained for AWS Lambda, Google Cloud Functions, and Azure Functions. The article outlines potential attack vectors for token exfiltration, including SSRF and RCE, and provides simulations demonstrating how tokens can be extracted and misused. Detection strategies are discussed, focusing on identifying serverless identities and anomalous behavior. Prevention measures are suggested, emphasizing the principle of least privilege and robust input validation. The article concludes by stressing the importance of understanding serverless credential mechanics and implementing proactive security measures to protect cloud environments.
