Mandiant warns that publicly exposed serverless applications often lack authentication and can lead to serious compromises in cloud environments. The report provides guidance on how to secure these vulnerable deployments, which are increasingly used in AI workflows.
Mandiant's assessments find that many serverless applications are exposed without proper authentication, often due to business needs. This exposure creates an opportunity for attackers to exploit application-level vulnerabilities like Local and Remote File Inclusion (LFI/RFI) and Command Injection. These attacks can lead to complete control over the cloud environment, giving attackers a foothold for further exploits.
The adoption of serverless architecture has been driven by the increasing use of generative AI technologies. Serverless applications, or Function-as-a-Service (FaaS), are being employed for numerous applications, including e-commerce and media. As their adoption rises, so does the urgency for securing these components against potential attacks.
Attackers targeting publicly exposed serverless workloads often seek to escalate privileges or move laterally within the environment. Techniques include extracting sensitive credentials stored within the application and exploiting vulnerabilities in the underlying code and libraries. Such access underscores the importance of comprehensive security strategies for serverless deployments.
Mandiant emphasizes the need for robust security practices tailored for serverless environments. The guidance offered focuses on hardening measures specific to Google Cloud Run services while noting that these principles are applicable to any publicly accessible serverless deployment. Ensuring proper authentication and regularly reviewing application code and third-party dependencies can help mitigate risks.
