Common API Abuse Tactics and Techniques in Public Sector Platforms

Brute Force Attacks

• Automated attempts to guess API keys, access tokens, and credentials

Cybercriminals often use brute force attacks as a common method for compromising an API. Attackers attempt to guess API keys, access tokens, or other authentication credentials through an automated process. By submitting multiple combinations of usernames and passwords, the attackers eventually identify the correct credentials that grant them unauthorized access to the API endpoints or sensitive data.

Distributed Denial of Service (DDoS) Attacks

• Overwhelming API endpoints with traffic from multiple sources

DDoS attacks target an API's infrastructure by flooding it with an overwhelming amount of traffic from multiple sources. Operating in a coordinated manner, a hacker commandeers multiple systems to send a continuous stream of requests to an API. As a result, the API becomes overwhelmed and can no longer respond to legitimate requests – slowing down or even crashing the services provided by the public sector platform.

Traffic Scraping and Data Harvesting

• Collecting valuable data from exposed APIs

Traffic scraping and data harvesting are tactics in which cybercriminals exploit vulnerable APIs to collect large amounts of valuable information. With many public sector platforms handling sensitive information such as personal data, financial information, or confidential strategic plans, these data breaches can result in significant consequences for the affected organizations and the individuals they serve.

API Injection Attacks

• Exploiting input validation vulnerabilities by injecting malicious code

API injection attacks occur when an attacker submits malicious code or commands through an API. This type of attack exploits vulnerabilities in an API's input validation mechanisms, allowing the attacker to bypass security controls and gain unauthorized access to sensitive data or execute arbitrary commands. Common forms of injection attacks include SQL injection, cross-site scripting (XSS), and command injection.

By gaining a clear understanding of these common API abuse tactics and techniques, public sector organizations can better assess their platforms' potential security vulnerabilities and take proactive measures to identify, prevent, and mitigate unauthorized access to their API ecosystems. Staying informed about emerging cybersecurity threats and trends is critical in developing robust defenses against API abuse and protecting the valuable data and services that public sector platforms provide.
