Puma Security Serverless Prey
Serverless Prey is a collection of serverless functions (FaaS), that, once launched to a cloud environment and invoked, establish a TCP reverse shell, enabling the user to introspect the underlying container:
- Panther: AWS Lambda written in Node.js
- Cougar: Azure Function is written in C#
- Cheetah: Google Cloud Function is written in Go
This repository also contains research performed using these functions, including documentation on where secrets are stored, how to extract sensitive data, and identify monitoring/incident response data points.
Disclaimer
Serverless Prey functions are intended for research purposes only and should not be deployed to production accounts. By their nature, they provide shell access to your runtime environment, which can be abused by a malicious actor to exfiltrate sensitive data or gain unauthorized access to related cloud services.
