In this second part, we demonstrate how a Cyber Resilience Act (CRA) assessment is performed in practice. Using a low-cost IP camera as an example, we show how a product is classified, how threats are modelled, how hardware and firmware are analysed, and how compliance gaps against IEC 62443-4-2 can be identified. You may want […]

In this blog article, we would like to share key insights from the “Defeating Microsoft’s Default BitLocker Implementation” security training by Hands-On Security and emphasize the potential risks and consequences associated with this attack technique. Our target audience includes businesses looking to safeguard sensitive data on their Windows devices, as well as individuals with an elevated requirement for protecting their data.
When accessing a remote server, one should always assume it has been compromised or might be in the near future. It is particularly crucial for users with administrative privileges to establish a secure connection to the Remote Desktop Protocol (RDP) service in order to not fall victim to credential theft or impersonation. To achieve this, there exist several measures in Windows. In this blog post, we’ll look at some of them, their benefits and their drawbacks.
Sometimes, the good old credential dumping techniques just won’t work. This is the story of how a bad actor could dump credentials on a fully-patched, monitored and hardened workstation.
The ntds.dit file from a domain controller contains all password hashes of the domain. In a company with employees around the globe we were allowed to analyze the hashes. Here are the results, and the reason why you should implement a banned password list.
BloodHound is the way to go to for finding attack paths in an Active Directory (AD) environment. However, it is not always clear how the data is gathered without looking at the code of SharpHound, the data ingestor for BloodHound. Microsoft hardened their systems over time through updates, which makes enumeration of Active Directory (AD) […]

A little bit over a year ago, I wrote an article on this blog about CVE-2020-1113 and how it enabled to execute code on a remote machine through relaying NTLM authentication over RPC triggering a scheduled task on the remote system. History repeats itself and a vulnerability of the same category has been fixed by Microsoft in June this year.
