Why are API attacks surging and how can organizations prevent them?

APIs (Application Programming Interfaces) have become a fundamental part of modern digital infrastructure, enabling seamless integration and communication between applications. However, the growing reliance on APIs has also made them a prime target for cyberattacks. Organizations across industries are experiencing a surge in API-related security incidents, making API protection a critical priority.

This week’s edition of the Journal will explore why API attacks have risen at such a rapid rate and what organizations can do to prevent them.

The rising threat of API attacks

APIs play an essential role in business operations, supporting everything from digital transactions to cloud computing. The increased adoption of APIs has also led to a rise in security vulnerabilities that cybercriminals exploit. According to AKAMAI, API attacks grew by 65% in the past year, with 4.8 billion attacks recorded in June 2024 alone.

Organizations operating in finance, healthcare, e-commerce, and other data-sensitive sectors are particularly vulnerable, as APIs often handle sensitive customer and business information. With API-driven services expanding globally, securing APIs has never been more critical.

But first, let us understand why organizations are frequently targeted by API attacks.

Why are organizations susceptible to API attacks?

The following are some of the main reasons why organizations become susceptible to API attacks:

• Increased reliance on APIs

  Organizations have become more dependent on APIs for business operations as they play a vital role in productivity and customer experience. The more APIs an organization uses, the greater the potential attack surface.

• Weak API security

  APIs that are not regularly assessed for vulnerabilities are easy targets for cybercriminals. Attackers may gain unauthorized access, inject malicious code, or overwhelm APIs with excessive requests (DoS attacks).

• Complex API environments

  As APIs become more complex, ensuring their security becomes more challenging, leading to unaddressed vulnerabilities.

• Lack of dedicated API security teams

  Securing APIs requires expertise in misconfiguration detection, authentication mechanisms, continuous monitoring, and protection against threats like DDoS and code injection. Many businesses lack in-house resources to conduct these assessments, leaving APIs exposed.

• Compliance requirements

  Regulatory bodies, including ISO 27001, GDPR, and PCI DSS, have introduced API-specific security requirements. Organizations failing to comply with these regulations risk data breaches and legal penalties.

   

What can organizations do to prevent API attacks?

The following are some best practices that organizations can implement to prevent API attacks:

• Regular security assessments and penetration testing

  Conduct periodic security assessments and penetration testing using real-world attack techniques to identify vulnerabilities before cybercriminals do.

• Behavior-based monitoring of APIs

  Implement continuous monitoring mechanisms to detect suspicious activities and anomalies in API traffic.

• Zero Trust approach for API access

  Enforce strict authentication and authorization controls, ensuring only verified entities can interact with APIs.

• Integrate API security into development operations

  Embed security into the API development lifecycle to catch vulnerabilities early.

• Mask sensitive information in APIs

  Prevent data exposure risks by masking sensitive information transmitted through APIs.

• Perform regular audits for compliance

  Ensure APIs adhere to the latest security standards and compliance regulations through regular audits.

   

With limited teams, resources, and tools, ensuring API security can be challenging. This is where organizations should seek assistance from experts who can provide the resources, tools, and expertise needed for early detection and prevention of API security risks.
