Password Spraying: Procedure, Risks, and Protective Measures

09/09/2025

Password spraying and credential stuffing are among the most common methods used by attackers to gain unauthorized access to company systems. Compared to classical brute-force attacks, password spraying attacks are more difficult to detect. They deliberately exploit the human weakness for easy-to-remember passwords. In this article, we explain how these attacks work, what risks they pose, and what measures companies can take to protect themselves effectively.

Purple Teaming: How to Strengthen Your Organization’s Cyber Resilience With Attack Simulations

11/08/2025

Purple teaming refers to the close cooperation between attacking (red team) and defending (blue team) security forces. Instead of acting independently, they jointly develop targeted attack scenarios, carry them out together, and analyze the results in direct exchange. This collaborative approach not only allows for vulnerabilities to be uncovered more efficiently but also addresses them directly with appropriate defensive measures.

Perfect 10: Discovery of Critical IBM AIX NIM Vulnerabilities (CVE-2024-56346 & CVE-2024-56347)

05/05/2025

During a recent penetration test of an IBM AIX environment, I uncovered two critical vulnerabilities, including one that had gone unnoticed for almost 30 years. The identified flaws in the AIX Network Installation Manager (NIM) allow for remote command execution with root privileges — potentially compromising entire AIX infrastructures. In this blog post, I will walk you through the discovery of CVE-2024-56346 and CVE-2024-56347, the impact of these vulnerabilities, and the steps you should take to secure your systems.

Cybersecurity Awareness as an Essential Part of Information Security

14/04/2025

In today’s cybersecurity threat landscape, it is no longer sufficient to rely on technical measures alone to ensure a company’s information security. From an organizational point of view, clear responsibilities and processes, as well as continuous testing of all these activities, are also required. Yet for cybersecurity, people are often the most vulnerable to attacks and this is precisely where cybersecurity awareness comes in: to train employees to recognize cyberattacks at an early stage and therefore to minimize the risks they pose to the company. This article explains why cybersecurity awareness is a central component of any Information Security Management System (ISMS), how organizations can benefit from appropriate awareness measures, and how important the engagement of top management is in this regard.

Passkeys: Why Passwords Have Probably Become Outdated

12/03/2025

An analysis of the most frequently lists of the most frequently used passwords shows that even today, passwords tend not to be very complex. This suggests that password managers, which would make it easier to create secure passwords, are rarely being used. As a consequence, many service providers rely on the addition of a second factor during the login process in order to reduce the dependency on the password. However, this solution is not an optimal measure as it does not fully address the problem of password security. A promising approach that could offer an alternative to passwords is the use of passkeys.
