Attack Surface Management in External Threat Intelligence

Every IT Security team needs access to some sort of Threat Intelligence (TI). It is an umbrella term for the collection of information and data on security risks and the threat actors behind them. Together, this information helps to prevent or limit incoming threats, and provides insights when mitigating an incident or event in Incident Response scenarios. As a deepening of the topic, External Threat Intelligence (ETI) mainly focusses on the combination of internal risk data with threat intelligence originating from outside of the organisation.

Swagger API: Discovery of API data and security flaws

APIs (Application Programming Interface) are used by applications to communicate and interact between systems, access data, and much more. It makes sure you get the correct response on a request. However, if someone were to intercept this request-response, they could potentially misuse the data or alter the process. Cyber-criminals scan the internet for unsecured APIs on a daily basis. If not properly secured, this can lead to unauthorised access to internal data or customer information. What’s more, in some cases it allows tampering with data directly from an exposed API. This technical article focuses on mapping and discovering Swagger APIs throughout the EU. We will present how we discovered those APIs and checked for misconfigured examples. We will illustrate each step using screenshots, present the results, and provide defensive recommendations. Research conducted by Soufian El Yadmani, Security Analyst at Cybersprint The interactive map below shows how many Swagger APIs we found, and in which region. You can click, drag and zoom to see how many Swagger APIs were found in your area.
