Enhancing Security for Sign-In with Ethereum: Phishing and Replay Attacks
Published: 2024-05-27 09:50:14

## Enhancing Security for Sign-In with Ethereum

As the use of blockchain technology expands, so does the adoption of innovative authentication methods like Sign-In with Ethereum (SIWE). While SIWE offers enhanced privacy and decentralization, it also presents unique security challenges. Two critical threats are phishing and replay attacks. In this blog post, we'll explore these risks and provide practical tips on how to mitigate them.

### Understanding Phishing Attacks

Phishing attacks are deceptive tactics used by attackers to trick users into providing sensitive information or signing messages on malicious sites. Here’s how these attacks work and what you can do to stay safe.

#### Malicious Sites

**Risk**: Attackers create fake websites that mimic legitimate ones, prompting users to sign in. Once the user signs a message, the attacker can use this information maliciously.

**Mitigation**:
- **Domain Verification**: Always verify the domain requesting the sign-in. Check the URL carefully to ensure it matches the expected domain. Legitimate sites often use secure (HTTPS) connections, indicated by a padlock icon in the browser's address bar.
- **Browser Extensions**: Utilize browser extensions such as MetaMask’s phishing detection, which can help identify and warn against malicious sites.

### Combating Replay Attacks

Replay attacks involve the reuse of a signed message to authenticate or execute transactions without the user's consent. Here's how these attacks happen and strategies to prevent them.

#### Nonce Usage

**Risk**: If a signed message lacks a unique identifier, it could be intercepted and reused by an attacker for multiple authentications.

**Mitigation**:
- **Include Nonces**: Incorporate a unique nonce (a one-time-use number) in each sign-in request. Servers should verify these nonces to ensure that each signed message can only be used once.

#### Session Management

**Risk**: Improper session management can allow attackers to reuse valid session tokens or messages.

**Mitigation**:
- **Unique Session Tokens**: Generate unique session tokens for each authentication request. These tokens should expire after a set period and be invalidated after use.
- **Timestamp Verification**: Include timestamps in signed messages to ensure they are used within a specific time frame. This limits the window of opportunity for an attacker to reuse a message.

### Conclusion

While Sign-In with Ethereum provides a promising alternative to traditional authentication methods, it’s crucial to address the associated security risks. By being aware of phishing and replay attacks and implementing the recommended mitigations, you can enhance the security of your SIWE implementations and protect users from potential threats. Stay vigilant, educate users, and continuously improve your security practices to safeguard against these evolving threats.

Unable to verify digital signature with public key and detached payload
Published: 2024-05-27 08:56:57

Hi Team,

I have a response from the external API in the below format:

const inputData = {
   signature: 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c',
   response: 'jdskhfgdjskfgkjsdhf'
};
The signature is without the payload check ("..") in inputData signature, and I am trying to verify the signature.

My public key format is:

PublicKey: {
   "kty": "RSA",
   "e": "AQAB",
   "use": "sig",
   "kid": "erityuiuerot",
   "n": "kjfghdsjkbfdasbf"
}
The inputData is:

const inputData = {
   signature: 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c',
   response: 'jdskhfgdjskfgkjsdhf'
};
I am using the below code to verify it in nodejs:

const jose = require("node-jose");

async function createKeystore() {
    const keystore = jose.JWK.createKeyStore();

    // Add the public key to the keystore
    const key = await keystore.add({
        kty: 'RSA',
        kid: "erityuiuerot",
        use: 'sig',
        alg: 'RS256',
        n: "kjfghdsjkbfdasbf",
        e: 'AQAB'
    }, 'json');

    return keystore;
}

async function verifyDetachedJWS(jws, payload) {
    try {
        const keystore = await createKeystore();
        console.log("keystore", keystore);
        // Use JWS.createVerify to verify the token
        const verifier = jose.JWS.createVerify(keystore);

       const result = await verifier.verify(jws);

        console.log('Verification successful:', result);
    } catch (error) {
        console.error('Verification failed:', error);
    }
}

// Example JWS token (without payload) and payload (replace with your actual values)
const jws = 'eyJhbGciOiJSUzI1NiIsImtpZCI6InNhbXBsZS1rZXktaWQifQ..SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c';


verifyDetachedJWS(jws, payload);
But I am getting the following error:

Verification failed: Error: no key found
    at processSig (/node_modules/node-jose/lib/jws/verify.js:132:22)
I am unable to figure out where the issue is. Can you please help me resolve this as soon as possible?

Do I need to use private for verification, if yes then please suggest code how to do it.

my private key is in below format :

PrivateKey : {
keys : [{
"p": "",
"kty": "RSA",
"q": "",
"d": "",
"e": "",
"use": "sig",
"kid": "",
"qi": "",
"dp": "",
"dq": "",
"n": ""
}]
};

Day 1 Pygomo Development - Lightweight framework for game development.
Tags: python, gamedev, opensource, development
Published: 2024-05-27 08:34:08

## :wave: Introduction

Hello Dev Community!

I'm excited to share a new project I’ve begun working on called [***Pygomo***][repository] - lightweight framework for game development (in Python). Although it's early days, but I'm eager to share my progress and plans to you! And your feedback, suggestions, and any contributions will be really appreciated :heart: !

## :rocket: The Journey So Far

The idea for Pygomo actually started back in January 21, 2024, under the name ***Pyndow***. Initially, it was envisioned as a *modern Python library for window management*. However, by February 4, 2024, the project's goal had changed, and the name was also changed to *Pygomo* to reflect its new goal of being a *lightweight framework for game development*.

Unfortunately, the development halted on February 9, 2024. Fast forward, just yesterday, I rekindled Pygomo with fresh enthusiasm and new ideas!

## :computer: Tech Stack

These are the tools and libraries I am currently using or will be using:

- **PDM**: For project and dependency management.
- **setuptools**: Used for running CMake with `setup.py` file.
- **pybind11**: To create Python bindings for C++ code.
- **CMake**: To manage the build process.
- **Ninja**: As the build system for CMake.
- **GLFW**: For window and input management.
- **GLEW** (or potentially **GLAD**): For loading OpenGL extensions.
- **OpenGL**: The core graphics library for rendering.
- **OpenAL**: For audio capabilities (haven't explored this yet, but it's on the roadmap).

## :chart_with_upwards_trend: Current Progress

~~Right now, I’m working on integrating *GLFW* and *GLEW* with *CMake* and *pybind11*.~~ I am integrating *GLEW*, because *GLAD* adds complexity to the building process (though I may switch back to GLAD). It’s very challenging so far, but there's progress. It's a rewarding process, and I'm excited for this to take shape.

## :star: What's Next?

> https://github.com/orgs/pygomo/projects/1

- Finalizing the integration of GLFW and GLEW (or GLAD) with CMake and pybind11.
- ~~Creating a *todo* to keep the ideas intact.~~
- Developing a window and input system with GLFW.

There's a lot more ideas that I have on my mind, I'll try to write them in the said [todo].

## :heart: Join The Journey

> https://github.com/pygomo/pygomo

I'm excited about the potential of Pygomo and would love to have the community involved. Again, I’m eager to hear feedback, suggestions, and any contributions from you!

Happy Coding!
