how i discovered akuma homura was in magia record

so magia record's twitter posted a link to an anniversary website said to contain hints at who its anniversary unit will be

throughout this website there were a few codes in base64, parts of a JWT token. as well, a series of numbers at the bottom.

when you go to the secret page of the site, it announces to you that you've found more hints. going back to the main section and sharing the contest-entrance tweet will get you an image with one of forty codes that correspond with one of those numbers. this is the one i got!

when you put all forty together, eventually, you'll get yourself a code. it is as follows:

O4W7TwhxYieUU8FFDPWv4FpkKnqmzRtl6TE9ps4dGWA

going back to the website, there's another sub-page called settoken, where you need to insert all the data you've found scrounging the site.

hitting set and going back to the secret page will bring you here.

the shield's ascii art is,

How to Protect Your Laravel App from JWT Attacks: A Complete Guide

Introduction: Understanding JWT Attacks in Laravel

JSON Web Tokens (JWT) have become a popular method for securely transmitting information between parties. However, like any other security feature, they are vulnerable to specific attacks if not properly implemented. Laravel, a powerful PHP framework, is widely used for building secure applications, but developers must ensure their JWT implementation is robust to avoid security breaches.

In this blog post, we will explore common JWT attacks in Laravel and how to protect your application from these vulnerabilities. We'll also demonstrate how you can use our Website Vulnerability Scanner to assess your application for potential vulnerabilities.

Common JWT Attacks in Laravel

JWT is widely used for authentication purposes, but several attacks can compromise its integrity. Some of the most common JWT attacks include:

JWT Signature Forgery: Attackers can forge JWT tokens by modifying the payload and signing them with weak or compromised secret keys.

JWT Token Brute-Force: Attackers can attempt to brute-force the secret key used to sign the JWT tokens.

JWT Token Replay: Attackers can capture and replay JWT tokens to gain unauthorized access to protected resources.

JWT Weak Algorithms: Using weak signing algorithms, such as HS256, can make it easier for attackers to manipulate the tokens.

Mitigating JWT Attacks in Laravel

1. Use Strong Signing Algorithms

Ensure that you use strong signing algorithms like RS256 or ES256 instead of weak algorithms like HS256. Laravel's jwt-auth package allows you to configure the algorithm used to sign JWT tokens.

Example:

// config/jwt.php 'algorithms' => [ 'RS256' => \Tymon\JWTAuth\Providers\JWT\Provider::class, ],

This configuration will ensure that the JWT is signed using the RSA algorithm, which is more secure than the default HS256 algorithm.

2. Implement Token Expiry and Refresh

A common issue with JWT tokens is that they often lack expiration. Ensure that your JWT tokens have an expiry time to reduce the impact of token theft.

Example:

// config/jwt.php 'ttl' => 3600, // Set token expiry time to 1 hour

In addition to setting expiry times, implement a refresh token mechanism to allow users to obtain a new JWT when their current token expires.

3. Validate Tokens Properly

Proper token validation is essential to ensure that JWT tokens are authentic and have not been tampered with. Use Laravel’s built-in functions to validate the JWT and ensure it is not expired.

Example:

use Tymon\JWTAuth\Facades\JWTAuth; public function authenticate(Request $request) { try { // Validate JWT token JWTAuth::parseToken()->authenticate(); } catch (\Tymon\JWTAuth\Exceptions\JWTException $e) { return response()->json(['error' => 'Token is invalid or expired'], 401); } }

This code will catch any JWT exceptions and return an appropriate error message to the user if the token is invalid or expired.

4. Secure JWT Storage

Always store JWT tokens in secure locations, such as in HTTP-only cookies or secure local storage. This minimizes the risk of token theft via XSS attacks.

Example (using HTTP-only cookies):

// Setting JWT token in HTTP-only cookie $response->cookie('token', $token, $expirationTime, '/', null, true, true);

Securing API Integrations: Best Practices for Contact Form Data Transmission

In today’s digital ecosystem, contact forms are more than just entry points for customer inquiries—they’re gateways to critical data that drive business operations. Whether the information is funneled into a CRM, ticketing system, or email marketing platform, the underlying mechanism that powers this is API integration. But with increasing cyber threats and stricter data regulations, securing the transmission of contact form data through APIs has never been more important.

This blog delves into the best practices for ensuring your contact form data is transmitted securely via API integrations, covering encryption, authentication, compliance, and more.

Why Securing Contact Form Data Matters

Contact forms often collect personally identifiable information (PII), such as:

Names

Email addresses

Phone numbers

Company names

Inquiry messages

Unsecured transmission of this data can lead to breaches, phishing attacks, or unauthorized access—exposing businesses to legal consequences and reputational damage. Secure API integration mitigates these risks and ensures data integrity, privacy, and compliance with laws like GDPR, HIPAA, and CCPA.

Common Threats to API-Based Data Transmission

Before diving into the best practices, it's important to understand the threats you’re defending against:

Man-in-the-middle (MITM) attacks – where data is intercepted between the contact form and the API.

Unauthorized access – due to poor authentication or exposed API keys.

Injection attacks – through unsanitized input, enabling attackers to manipulate API calls.

Data leakage – from insecure storage or logging mechanisms.

Replay attacks – where a malicious user resends legitimate API requests to gain unauthorized access or cause disruptions.

Best Practices for Securing API Integrations with Contact Forms

1. Use HTTPS with SSL/TLS Encryption

The first and most critical step is to ensure all communication between the form, your server, and any third-party APIs happens over HTTPS. HTTPS encrypts the data in transit, making it nearly impossible for attackers to intercept and read sensitive information.

Pro tip: Use strong TLS configurations and ensure your SSL certificate is up to date.

2. Implement Strong Authentication and Authorization

APIs must be protected by robust authentication mechanisms. Relying solely on static API keys can be risky if they’re not stored securely or become exposed.

Best practices include:

OAuth 2.0 – A widely accepted protocol for secure delegated access.

JWT (JSON Web Tokens) – Allows secure transmission of claims between parties.

IP whitelisting – Restrict API access to known IP addresses.

Role-based access control (RBAC) – Ensure only authorized applications and users have access.

3. Validate and Sanitize Input Data

Never trust data coming from a user-facing contact form. Always validate and sanitize inputs before processing or transmitting them to an API to prevent injection attacks.

Validation examples:

Use regex patterns to validate email formats.

Limit message length to prevent buffer overflows.

Sanitize inputs by removing or escaping special characters.

4. Rate Limiting and Throttling

Implement API rate limiting to protect your integration from abuse. Bots or attackers may try to flood your endpoints with traffic, potentially leading to denial-of-service (DoS) attacks or data scraping.

Suggested limits:

Max 60 requests per minute per IP

Max 1000 requests per day per user

Use appropriate HTTP response headers like 429 Too Many Requests to inform clients of limits.

5. Encrypt Data at Rest and in Transit

While HTTPS encrypts data in transit, you should also encrypt sensitive data at rest if you're storing it temporarily before pushing it to an API.

Encryption standards to consider:

AES-256 for data at rest

TLS 1.2 or higher for data in transit

Never store unencrypted form submissions on disk, in logs, or database tables.

6. Use Web Application Firewalls (WAFs)

A WAF helps filter out malicious requests to your contact form and API endpoints. They block suspicious IPs, detect bots, and protect against common OWASP Top 10 threats.

Features to look for:

SQL injection protection

Cross-site scripting (XSS) filters

Geo-blocking for unknown regions

Cloudflare, AWS WAF, and Sucuri are popular options.

7. Secure API Keys and Secrets

API credentials should never be hardcoded into frontend code or exposed in browser-accessible scripts. Instead:

Store secrets in server-side environment variables.

Use secret management tools like HashiCorp Vault or AWS Secrets Manager.

Rotate keys periodically and revoke unused credentials.

8. Enable Logging and Monitoring

Real-time monitoring can alert you to anomalies like spikes in traffic or repeated failed API calls, indicating an attack or integration issue.

What to log:

Timestamped request metadata

Status codes and error responses

Authentication failures

Ensure logs themselves do not store sensitive information, and secure them with proper access control.

9. Implement CSRF and CAPTCHA Protection

To prevent bots and malicious actors from abusing your contact form, use:

CSRF tokens to verify that a submission originated from your site.

CAPTCHAs or reCAPTCHA to block automated submissions.

This reduces the risk of your API being bombarded with spam or test payloads.

10. Follow the Principle of Least Privilege

Only allow the contact form integration to access what it absolutely needs. If the form only needs to create a lead in a CRM, don’t give it permission to delete or modify records.

This principle minimizes potential damage if credentials are compromised.

11. Secure Third-Party Services

If your contact form integrates with external APIs (e.g., HubSpot, Mailchimp, Salesforce), ensure these services:

Use HTTPS exclusively

Provide granular API scopes

Offer audit trails

Comply with regulations like GDPR and SOC 2

Always vet vendors for their security posture before integration.

12. Test for Vulnerabilities Regularly

Conduct regular penetration testing and vulnerability scans to uncover weak spots in your form and API integration. Include both automated tools and manual ethical hacking.

Tools to try:

OWASP ZAP

Burp Suite

Postman Security Testing

Fix any discovered vulnerabilities immediately and document the fixes.

13. Comply with Data Protection Regulations

Different regions have specific laws about how user data should be collected, stored, and transmitted. For example:

GDPR (EU): Requires explicit user consent and secure handling of PII.

CCPA (California): Grants users the right to know and delete their data.

HIPAA (US): Regulates health-related data.

Make sure your API-based contact form integration complies with relevant laws, especially if collecting data from users in regulated industries.

14. Include a Clear Privacy Policy

Your contact form should link to a privacy policy explaining:

What data is collected

How it will be used

Where it will be transmitted

How long it will be stored

This not only ensures compliance but also builds trust with users.

15. Fail Gracefully and Securely

Even with all protections, failures can occur. Ensure your contact form and API integration handle errors securely:

Don’t expose stack traces or internal server information in error responses.

Avoid leaking API credentials in logs or responses.

Inform the user of a failure without revealing system details.

Use secure error handling to maintain a good user experience while protecting your backend.

Conclusion

Securing API integrations for contact form data transmission is not optional—it’s a necessity in a world where data breaches are commonplace and user privacy is paramount. From implementing HTTPS and strong authentication to input validation and compliance, each layer of protection contributes to a robust, secure system.

Organizations that proactively secure their contact form integrations not only protect themselves from cyber threats but also enhance their credibility and user trust. By adopting these best practices, you're not just guarding data—you're safeguarding your brand.
