Understanding API Attacks and Your Security Risks
API attacks are attempts to exploit Application Programming Interfaces (APIs) for malicious purposes, such as gaining unauthorized access to sensitive information or disrupting services. Given the rising trend of APIs being exploited as pathways for malicious attacks, implementing robust API security measures is a necessity to protect your enterprise from potential harm.
Types of API Attacks
API attacks can manifest in various forms, including some common API attack types:
- DDoS attacks: attempt to overwhelm an API’s memory by initiating numerous connections simultaneously, increasing the attack surface and potentially causing service disruptions.
- Man-in-the-Middle (MITM) attacks: adversaries intercept the communication between an API endpoint and a client, enabling them to steal confidential information or modify transmitted data.
- Injection attacks: malicious code is injected into an API request, allowing attackers to execute unauthorized commands or access sensitive data.
- Data exposure: sensitive data is exposed through vulnerabilities in the API, such as improper access controls or insecure data storage.
It is important for developers and API providers to be aware of these attack vectors and implement appropriate security measures to protect against them.
Injection attacks represent another prevalent form of API assaults where malevolent entities insert code like SQLi (SQL injection) and XSS (cross-site scripting) into software for unauthorized access. Excessive data exposure, on the other hand, occurs when sensitive data is left exposed on the server, allowing unauthorized access to the information.
Authentication hijacking is a more targeted attack that attempts to circumvent or break the authentication methods employed by a web application, potentially leading to data breaches and privacy violations. Attackers can exploit vulnerabilities in authentication mechanisms to gain access, gain unauthorized access to secured resources, and compromise user accounts.
The Role Bots Play in API Attacks
Like any use of malicious automation during any type of attack, bots are leveraged for their blend of ease of use, sophistication, and cost-effectiveness. Bots allow adversaries to launch API attacks at scale. Carrying out malicious actions far faster than a human could. If APIs are not protected against automation it leaves them vulnerable to attackers’ favorite tool.
Consequences of API Attacks
API attacks can lead to serious outcomes including compromised data, interrupted services, and damage to your organization’s reputation. For instance, during a Man-in-the-Middle (MITM) attack, a hacker can intercept session tokens issued by a session token issuing api, providing them with access to the user’s account and potentially exposing a large amount of sensitive and personal information.
API breaches can have a considerable financial impact, particularly in the financial services industry. Research indicates that vulnerable APIs can cost organizations up to $75 billion annually in losses due to disruption. The exploitation of API vulnerabilities can lead to:
- Unauthorized data access
- Interception
- Manipulation
- Disruption of services
These consequences can result in financial losses and damage to a company’s reputation.
API Security Vulnerabilities
API security vulnerabilities refer to weaknesses in an API that could be potentially leveraged by malicious entities to access sensitive data or carry out unauthorized activities. One potential weakness in API security lies in authentication and authorization, where API calls utilize access tokens to verify non-human “users”, but these tokens may be compromised due to various factors. Organizations should adopt a “zero-trust” approach to cyber security and follow an api security checklist. An important priority must be placed on developing and enforcing strong access control measures.
Another considerable factor contributing to API security vulnerabilities is the improper validation of input. Traditional vulnerability scanners are often unable to detect common logical vulnerabilities in APIs, including injection, logical workflow, and parameter attacks during automated security audits. Without proper Transport Layer Security (TLS) implementation, malicious actors have the potential to intercept and modify the data passing through the API, jeopardizing the confidentiality and integrity of the exchanged information, especially when they transfer sensitive data.
Recent API Breaches Underscore API Risk
The spotlight has been put on the significance of robust API security measures due to recent high-profile API breaches involving:
- Optus
- 3Commas
- Beetle Eye
- Dropbox
- FlexBooker
- Texas
These breaches have exposed vast amounts of sensitive user records, resulting in data leaks, financial loss, reputational harm, and internal HR repercussions.
The consequences of API breaches can be far-reaching, impacting not only the affected companies but also their customers, partners, and even regulators. Organizations must prioritize API security by:
- Implementing authentication and authorization protocols
- Utilizing encryption
- Monitoring API usage
- Employing bot management software to protect automated threats targeting APIs.
Why API Security Incidences are Becoming More Common
The widespread use of APIs has given attackers increased opportunities to exploit vulnerabilities and compromise authentication controls, leading to data exfiltration and other disruptive activities. There has been a notable increase in the number of unique attacks reported in recent years, as well as an increase in attack traffic. Furthermore, a large percentage of attacks occur over authenticated APIs, indicating that attackers are specifically targeting these entry points through malicious API requests.
The increasing reliance on APIs has made them a prime target for attackers, who are becoming increasingly sophisticated in their methods. Advanced techniques such as AI-driven threat detection, machine learning algorithms, and blockchain are being used to exploit APIs. The lack of proper tools to secure APIs and the increasing ubiquity of APIs contribute to their vulnerability.
Attacks are increasingly easier to conduct at scale. Through the use of automation bot operators are able to launch affordable and sophisticated attacks. This combined with the widespread use and reliance on APIs makes them a prime target for automated attacks.
Typically, attackers employ methods such as brute force attacks, API abuse, and man-in-the-middle (MITM) attacks to exploit APIs. The combination of these factors, coupled with the increasing number of APIs used by organizations, has contributed to the rise in API security incidents.
The Challenges with Securing APIs
It’s so complex to secure APIs because of their increasing number and unique security needs. Traditional security technologies, such as web application firewalls (WAFs), are limited in their ability to protect APIs from risks stemming from business logic flaws. Security incident event management (SIEM) tools, while useful for aggregating data from security technologies, cannot detect abnormal activity in APIs without a dedicated API security tool.
Monitoring APIs is essential for understanding the movement of data between applications and amplifying the number of locations that security teams need to keep an eye on. Unfortunately, traditional security technologies are often ill-equipped to address the complexity and layered nature of APIs, as well as their unique security requirements, including visibility, effectiveness against API sprawl, and detection of business logic attacks.
To overcome these challenges, organizations must adopt specialized API security tools and strategies that focus on the unique requirements and vulnerabilities of APIs. These tools should provide continuous monitoring, high-fidelity alerts, bot management software, and protection against a wide range of API attacks to secure the ever-expanding API landscape.
Strengthening API Security with Bot Management
Bot management serves as a necessary layer of defense to secure enterprise APIs by:
- Identifying and blocking malicious traffic
- Offering advanced bot detection
- Providing behavior-based protection
- Ensuring API security
- Preventing credential stuffing
- Preventing content scraping
- Utilizing global threat intelligence
Bot management software employs various techniques to detect and prevent malicious traffic. Kasada’s bot management software works by detecting the malicious automation used by attackers. Kasada deploys hundreds of sensors to collect hidden traces of this automation. The solution uses this data to identify and block malicious automation. While ensuring the data collected by sensors has not been tampered with, limiting false positives.
Using a highly obfuscated code the data collected is hidden from attackers attempting to reverse engineer the protection. Kasada goes one step above and adds a layer of security with the sensors used to detect the automation changes between each request. This ensures that even if an attacker can reverse engineer Kasada’s code, what they gain will have already been outdated, which means Kasada has eliminated motivation and repeat attacks are out of the question.
