API security.

Last year breaches involving big names like T-Mobile and Honda have thrown this topic into sharp focus, and rightfully so.

Insecure APIs can expose sensitive customer data, leading to a nightmare of identity theft, phishing attacks, and reputational damage for your company.
Last year, we wrote that API Security is a top concern for businesses and organizations.

It seems like that behind the scenes there lies a dark and overlooked aspect of API Security.

T-Mobile Data Breaches

T-Mobile disclosed two data breaches in 2023, affecting millions of customers. The first breach, disclosed on January 19, 2023, impacted 37 million customers, while the second breach, disclosed on June 23, 2023, affected 836 customers.

Nature of Breaches

• The attacker exploited a vulnerability in an API to steal the personal information of customers, including names, phone numbers, email addresses, and account PINs.
• The second breach involved the exploitation of a vulnerability in T-Mobile's website to gain access to the personal information of customers.

Impact

• Both breaches exposed affected customers to the risk of identity theft and phishing attacks.
• T-Mobile offered affected customers two years of free credit monitoring and identity theft protection.

Prior Incidents

• T-Mobile also experienced email server hacks in 2020 and unauthorized access to customer proprietary network information in 2021.

Honda API Flaws Security Incident

Security researcher Eaton Zveare discovered two vulnerabilities in Honda's e-commerce platform for power equipment, marine, lawn & garden, which allowed unauthorized access to customer data and admin panels.

Vulnerabilities

• The discovered vulnerabilities enabled anyone to reset the passwords of any account on the platform and access the admin panels of all Honda dealers.
• The vulnerabilities were caused by a lack of access controls on the platform, allowing unauthorized access to sensitive data.

Data Exposure

• The password reset vulnerabilities could have exposed customer data such as names, addresses, email addresses, and phone numbers.
• The admin panel vulnerabilities could have exposed even more sensitive data, such as dealer sales figures, inventory levels, and customer purchase history.

Response

• The vulnerabilities were discovered in January 2023 but were not disclosed until June 2023, indicating a delayed response to the security issues.

Importance of Security

• The incident serves as a reminder of the importance of security for businesses and the need to carefully review security practices to protect customer data.

These incidents highlight the critical need for robust API security measures, proactive adoption of best practices, and timely response to security vulnerabilities to protect customer data and maintain a safe and trusted environment.

Why API Security Matters More Than Ever

The incidents involving T-Mobile and Honda underscore the critical importance of API security. Businesses and developers must prioritize the security of their APIs to safeguard sensitive customer data. To delve deeper into the intricacies of API security, our article on the untold secrets of API security goes into detailed exploration.

Insecure APIs pose significant risks, including data breaches, financial loss, reputational damage, and legal implications, highlighting the urgent need for robust API security measures.

Here's why you should prioritize API security:

1. Comprehensive API Inventory and Documentation: Identify and document every API in your ecosystem to gain a thorough understanding of the API landscape.
2. Strong Authentication and Authorization: Ensure that APIs require proper credentials, such as tokens and certificates, for access, thereby mitigating unauthorized access and potential breaches.
3. User Input Validation: Implement robust user input validation to sanitize data and prevent injection attacks and other vulnerabilities, enhancing the overall security posture of your APIs.
4. Encryption of API Traffic: Protect data in transit between clients and servers by employing HTTPS to encrypt all API traffic, safeguarding sensitive information from unauthorized access.
5. Regular Vulnerability Testing and Scanning: Conduct regular penetration testing and security audits to identify and address weaknesses in APIs, thereby ensuring proactive mitigation of potential vulnerabilities.
6. Continuous Monitoring for Suspicious Activity: Implement robust monitoring of API activity to track access patterns and detect anomalies that might indicate potential breaches, allowing for timely intervention and response to security threats.

Best Practices for API Security

To improve API security, businesses and developers should implement robust security measures such as API authentication, encryption, and access control.These measures help prevent unauthorized access and protect sensitive data from potential breaches.
Here are some key practices to fortify your API security:

Customer Trust

Customer data is a valuable asset, and breaches due to insecure APIs can severely impact trust. A breach shakes that trust, potentially leading to customer churn and long-term damage to the business's reputation.

Compliance Risks

Data privacy regulations such as GDPR and CCPA carry substantial legal and financial consequences. Breaches resulting from insecure APIs can lead to hefty fines and reputational damage, making compliance a crucial aspect of API security.

Vulnerability to Attacks

Insecure APIs are a prime target for attackers, posing a significant risk of exposing vast amounts of customer data, as evidenced by the breaches at T-Mobile and Honda.

Automated Security Checks

• These checks identify vulnerabilities and categorize the request's threat level as low, medium, or high.
  • SQL Injection: Treblle analyzes the payload sent with every API and detects the most common SQL injection patterns.
  • IP Reputation: Treblle uses its own network as well as 3rd party services to check the reputation of your user's IP address.
  • Authorization: Treblle can automatically detect all forms of authorization on every API request and check to make sure it's being used properly.
  • Secure Connection (SSL/TLS): Treblle automatically detects whether or not the requests your end customers are making are using HTTPs instead of HTTP.
  • IDs vs. UUIDs: By examining the request URL, Treblle can automatically detect whether or not you're using IDs on your endpoints.
  • Rate Limiting: Treblle looks for the x-rate limit-* headers in the response payload to see if you correctly use rate limiting.
  • Content Labeling: Treblle checks to see if the Content-Type header exists and if its value is set to application/json.
  • MIME Sniffing: Treblle checks to see if the X-Content-Type-Options header exists and if its value is set to nosniff.
  • Force Secure Connection: Treblle looks for the strict-transport-security header in your API responses.
  • Embedding Prevention: Treblle checks to see if the X-Frame-Options header exists and its value is set to deny.
  • Security Policies: Treblle checks to see if the response headers for your requests have a Content-Security-Policy header defined.
  • Content Type Specification: Treblle checks the headers of your request to see if the Accept header exists and if its value is set to application/json.
