It’s been two weeks since Microsoft released a patch for the Exchange vulnerabilities. For many, the dust has settled. Others are still fighting fires. Today, I’d like to look back at some of the problems we saw. Some were expected, other surprised us. I’ll go over them, and give tips on how these problems can be avoided in the future.

Today, supply chain attacks are as abundant as they are elusive. However, as many parties communicate about the dangers and their technical solutions, not much is said about the basics of supply chains attacks. I have written this article based on my personal experiences knowledge on the subject. I hope it answers most of your questions about the topic, so that you have a solid basis to expand your supply chain security from.

In this blog, we'll cover our attack surface management approach compared to five existing security approaches. What methods do they share? And where do they complement each other? We'll have a look at these techniques:  1. Asset discovery 2. Vulnerability management 3. Penetration testing 4. Red teaming 5. Supplier security governance Each has some touch points with attack surface management. For this comparison, we build on our earlier explanations of the concept. In the first blog, we gave our definition and summarised what drives the need for the solution. You can read our second blog to see how attack surface management is positioned with regards to 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.

The year 2020 has brought us many different events and experiences, all with varying levels of impact. Physical events have impacted the digital world, and cybersecurity incidents have had their effect on the way we live. Remember the Citrix incident early this year? That prohibited many from working remotely, resulting in massive rush hours traffic jams as everyone travelled to the office. Almost the exact opposite of what COVID-19 has done to our way of working. But what does this mean for 2021's cybersecurity? And what evolving threats should you prepare for? Three cybersecurity CEOs share their views, predictions, and tips. 

The web is in a continuous state of dynamic development, with websites being created, updated, and deleted every day. These websites are the digital equivalent of a rented property. Similar to physical properties, visitors will need a precise address to visit you.

It's the term we use the most: Attack Surface Management. It is the foundation of your organisation’s digital infrastructure. It’s the starting point of your IT security policies, configuration database management, vulnerability mitigation, and much more. In this blog, we’ll shortly describe what drives the need for an Attack Surface Management solution, share our definition of the term attack surface, and explain how it minimises the risks to your brand.

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.    

PostNL is the largest mail order and delivery organisation in the Netherlands, also operating in Belgium and Luxemburg. It has made mail and parcels accessible for over 220 years, growing to become one of the largest private employers in the Netherlands. Over the years, the organisation has grown through expansions, mergers and acquisitions, making its attack surface rather complex. Gunther Cleijn, Cyber Security Officer explains how he and his team work to ensure the security and daily productivity of the organisation.
