Cloudflare is famous among developers as a leading CDN to efficiently deliver customer facing Internet content for their applications, but Cloudflare can also be used to verify all incoming requests before they reach your API server, by leveraging Cloudflare workers.
In my previous article, we saw how to bypass certificate pinning within a device you control and, as promised, we will now see how you can protect yourself against such an attack.
In this article you will learn how to use a mobile app attestation service to protect your API server from accepting requests that come from a mobile app where certificate pinning has been bypassed. This means that even though the attacker has bypassed the certificate pinning, he will not be able to receive successful responses from the API server. Instead, the server will always return 401 responses, thus protecting your valuable data from getting into the wrong hands.
In a previous article we saw how we could steal an API key by performing a man in the middle (MitM) attack to intercept the https traffic between the mobile app and the API server. In this article we will learn how to mitigate this type of attack by using a technique known as certificate pinning.
In order to demonstrate how to use certificate pinning for protecting the https traffic between your mobile app and your API server, we will use the same Currency Converter Demo mobile app that I used in the previous article.
In this article we will learn what certificate pinning is, when to use it, how to implement it in an Android app, and how it can prevent a MitM attack.
This walk-through will show how simple it is to integrate Approov in a stateless API server using Java and the Spring framework.We will see the requirements, dependencies and a step by step walk-through of the code necessary to implement Approov in a Java Spring stateless API.
EVALUATING GRPC REQUEST-RESPONSE, AUTHENTICATION, AND STREAMING
gRPC is an open source remote procedure call (RPC) framework that runs across many different client and server platforms. It commonly uses protocol buffers (protobufs) to efficiently serialize structured data for communication, and it is used extensively in distributed and microservice-based systems.
