API Security Trends and Projections for 2024
Prepare for evolving threats with comprehensive measures and proactive vigilance.
Samantha Cowan, Director of Information Security at Nylas, highlights the escalating API vulnerabilities in 2023 and outlines crucial strategies to safeguard against emerging threats in 2024.
As the digital landscape continues to evolve, the latter half of 2023 has brought critical developments in API (Application Programming Interface) security to light. The increasing reliance on APIs has made them a focal point for cybersecurity efforts. This period has seen a notable rise in vulnerabilities, bringing new challenges and learnings for the industry.
In the following sections, we will delve deeper into these trends, exploring the limitations of standard frameworks in addressing these emerging threats, the urgency of leak protection, strategic recommendations for rising threats, and case studies from 2023 that provide valuable insights for businesses. We will also look ahead to potential threat vectors for 2024, preparing for the evolving challenges in API security.
API Trends
1. The pervasiveness of API vulnerabilities
The Wallarm API ThreatStats report for Q3 2023 revealed 239 new API vulnerabilities, indicating a growing concern in API security. Notably, 33% of these vulnerabilities pertained to Authorization, Authentication, and Access Control (AAA), underlining the importance of robust AAA protocols in safeguarding API interactions. These vulnerabilities, if exploited, can lead to major security breaches.
The report identified the most common threats as injections, authentication flaws, cross-site issues, and other vulnerabilities related to resource consumption, secrets management, cryptographic weaknesses, and session management. The existence of such vulnerabilities necessitates continuous vigilance and the regular updating of security protocols. It also emphasizes the need for ongoing training for developers and security teams to keep pace with emerging threats and security best practices.
2. Limitations of standard frameworks
While foundational, traditional frameworks like the OWASP API Security Top-10 have limitations in addressing the dynamic nature of API threats. The advancement of technology and the emergence of sophisticated cyber threats necessitate a more agile and real-time approach to API security that can quickly identify and mitigate new threats as they arise.
3. Leak protection
The report highlighted the critical need for enhanced API leak protection, especially considering significant breaches at companies like Netflix and VMware. These incidents underscore the serious risks API leaks pose to data security and privacy. To address this, businesses must adopt proactive security strategies, such as implementing advanced leak detection systems, practicing secure coding, and conducting regular audits to identify and fix vulnerabilities. A vigilant, multi-layered approach to API security is essential for protecting sensitive information and upholding customer trust.
4. Rising threats and strategic recommendations
The Wallarm report identified injections as the most pressing API threat, underscoring their likelihood of significant damage. It also stressed the need to expand defensive strategies beyond the scope of existing OWASP guidelines. This shift is crucial due to the rapidly evolving nature of API security risks. Organizations are encouraged to adopt more dynamic, comprehensive measures that address traditional vulnerabilities and anticipate and mitigate emerging threats. This approach calls for continuously reassessing security practices and adopting advanced threat detection tools.

Case Studies
1. Netflix’s dispatch
Overview: Netflix’s Dispatch experienced JWT secret exposure in error messages, through which any platform using Dispatch could be compromised by attackers.
Cause: The breach was traced back to an API vulnerability that allowed unauthorized access to sensitive JWT Secret Key.
Impact: Any Dispatch users who own their instance and rely on the `Dispatch Plugin – Basic Authentication Provider plugin for authentication may be impacted, allowing any account to be taken over within their instance. This led to a loss of trust among Dispatch users.
Lessons Learned:
- Regularly auditing APIs for vulnerabilities is crucial.
- Strengthening authentication and authorization processes can help prevent unauthorized access.
- Having a swift response plan in place can mitigate the impact of a breach.
2. VMware
Overview: VMware, a cloud computing and virtualization company, fell victim to an information disclosure API vulnerability in its VMware Tanzu product.
Cause: The exploit was linked to a security flaw in one of their widely used APIs, which was not adequately secured against injections.
Impact: A malicious user with access to the platform system audit logs can access API admin credentials and push new malicious versions of an application. The exploit led to the theft of proprietary data and disrupted services.
Lessons Learned:
- Continuously monitoring and patching vulnerabilities in APIs is essential.
- Keeping abreast of the latest security threats and trends can help in early detection and prevention.
- Advanced security solutions like real-time monitoring and automated threat detection can provide additional protection.
3. Twitter
Overview: It was discovered in January 2023 that between June 2021 and January 2022, a flaw existed in Twitter’s API, enabling attackers to input contact details such as email addresses and obtain the corresponding Twitter account if it existed.
Cause: The breach was linked to a security flaw in one of their API endpoints, which did not have adequate authorization and authentication checks.
Impact: Email addresses of approximately 200 million Twitter users are sold for as little as $2 on the dark web.
Lessons Learned:
- Strengthening authentication and authorization processes can help prevent unauthorized access and unwanted information disclosure.
- Regularly auditing APIs for vulnerabilities is crucial.
- Having a swift response plan in place can mitigate the impact of a breach.
Potential 2024 Threat Vectors
As we approach 2024, the landscape is expected to encounter new and evolving threats. Understanding and preparing for these potential threats is crucial. Here’s an overview of anticipated threat vectors for 2024:
- Advanced injection attacks: Injection threats are likely to grow more sophisticated, exploiting complex vulnerabilities in API structures. These attacks could involve advanced SQL, XML, and command injections, targeting the deeper layers of API integrations.
- Exploitation of microservices architectures: With the increasing adoption of microservices, APIs that facilitate communication between these services may become prime targets for attackers.
- API gateway vulnerabilities: Gateways will become attractive targets as the central point of access control and management for APIs. Exploiting vulnerabilities in API gateways could allow attackers to bypass security controls and access sensitive data.
- Data leaks: The increase in data-centric APIs will lead to a higher risk of data leaks.
- Machine learning model attacks: As AI and machine learning models become more integrated with APIs, attackers might focus on manipulating these models through the API layer, leading to skewed or compromised AI decisions.
- Rate limiting and denial of service: Attacks focused on overwhelming APIs with high traffic volumes could disrupt services and lead to denial.
- API-specific ransomware: A new breed of ransomware targeting API vulnerabilities may emerge.
- Zero-day vulnerabilities: Unprecedented vulnerabilities in popular API frameworks and libraries might be discovered and exploited before patches or solutions can be implemented.
- Compliance and regulatory challenges: Evolving compliance requirements, especially in data protection and privacy, will pose significant challenges in API management, with the risk of non-compliance leading to vulnerabilities.
Navigating the Evolving Landscape of API Security
The trends and developments in API security observed in the latter half of 2023 paint a picture of a rapidly evolving digital threat landscape. 2023 saw a significant rise in API vulnerabilities, emphasizing the need for enhanced security measures. The increasing prevalence of sophisticated threats such as injections, authentication flaws, and cross-site issues requires a proactive and dynamic approach to security.
The trends and cases from 2023 and the projections for 2024 underscore the importance of a comprehensive, multi-layered approach to API security. Organizations must be agile, informed, and prepared to adapt their security strategies to address current and emerging threats. By doing so, they can protect their digital assets and ensure the privacy and security of their users in an increasingly interconnected world.
