Race conditions arise when two or more processes access the same resource simultaneously and the result depends on the order in which the operations occur. For example, two parallel requests can redeem the same coupon if both check its status as “not yet used” before either request records the redemption in the database.
Taking advantage of Software-as-a-Service (SaaS) without losing control over sensitive data is a longstanding dream. Companies often rely on third-party providers to protect their most sensitive data or workloads. However, this leads to compliance and trust issues. SaaS models based on confidential computing promise to resolve this conflict: Companies should be able to take advantage of the flexibility of SaaS without compromising the confidentiality of their data.
The ransomware landscape is constantly changing. New groups emerge, while old ones disappear or reorganize. However, only a few of these new players manage to establish themselves within a short period of time. One such group is BravoX, which first appeared publicly in early 2026 and was involved in several incidents shortly thereafter – including cyberattacks that we at Oneconsult had the privilege to handle.
It’s Tuesday morning. Your robot vacuum is quietly doing its rounds while you’re in a meeting – a perfectly ordinary situation that you don’t give a second thought to. After all, it’s just a device, a little convenience. To an attacker, however, this very robot vacuum isn’t just an everyday helper – it’s a gateway into your network. It is precisely this scenario that has EU lawmakers concerned, which is why they drafted the Cyber Resilience Act (CRA). This law also applies to Swiss companies that sell, import, or distribute products with digital elements throughout the EU.
Artificial intelligence (AI) has advanced rapidly in recent years. While in 2023 it still consisted mainly of simple chatbots – with OpenAI’s ChatGPT being the prime example – it has evolved into an ecosystem of highly complex, autonomous systems. Today, companies are deploying AI applications across various business areas: from intelligent customer support chatbots and retrieval augmented generation (RAG) systems to fully autonomous AI agents that independently plan tasks, access tools, and make decisions.
Mobile applications have become an integral part of our daily lives and are growing increasingly important for businesses, especially in industries that handle highly sensitive data. A recent example from the banking sector illustrates this clearly: Over 10 % of the Swiss population now uses neo banks (linked page in German) – banks that typically interact with their customers exclusively through a single mobile application.
The IT systems of modern companies are highly connected, distributed, and dynamic. Cloud services, SaaS applications, home office, different locations, and external partners expand digital value creation – but also increase the attack surface. Consequently, the number and complexity of cyberattacks are increasing, as are regulatory requirements and expectations for rapid response capabilities.
Cyberattacks are on the rise – and they no longer only affect large corporations. Small and medium-sized enterprises (SMEs) are also increasingly becoming the target of cybercriminals. In the event of an emergency, a lack of processes, unclear responsibilities, or insufficient preparation often lead to delays, unnecessarily high costs, and considerable reputational damage.
What was considered unlikely just a few years ago is a reality today: the majority of companies have already been affected by cyberattacks, many of them successfully. The question is therefore no longer whether a security incident will occur, but when it will happen and how resilient your company will be in responding to it through professional incident response management (IRM).
It has now been over ten years since Tim Medin introduced the so-called Kerberoasting attacks. And even today, Kerberoasting remains a reliable attack technique against Microsoft Active Directory, which is often exploited by penetration testers and red teamers. With a valid domain account, the attack can be carried out in an Active Directory environment without extended privileges. Afterwards, an attempt can calmly be made to crack the passwords of service accounts offline.
IBM has addressed newly discovered critical vulnerabilities in AIX Network Installation Manager (NIM) with the release of security patches, following responsible disclosure by Oneconsult’s security research team.
Over the course of 2025, virtually everyone (in IT) started talking about Post-Quantum Cryptography (PQC) and the Q-Day. In this article, we will cut through the headlines, explain to you what all this is about, and provide recommendations on how to deal with it.
The end of support for Windows 10 on 14 October 2025 has (hopefully) prompted many companies to migrate to Windows 11. In this context, it would also make sense to switch the device management to Microsoft Intune and manage the Windows 11 hardening policies there as well. With a properly configured hardening baseline, the attack surface of Windows systems can be significantly reduced.
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 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.
Whether it’s threatened DDoS attacks, data leaks, or sextortion scams – cybercriminals often demand payment via Bitcoin wallet addresses. It’s the (supposed) anonymity of cryptocurrency that makes it particularly attractive for extortion attempts.
Did you know that PDF files often serve as a gateway for cyberattacks? These seemingly harmless documents can be infected with dangerous viruses that damage to your computer without you realizing it – so called PDF phishing. Viruses often hide in PDF files to exploit security vulnerabilities and steal your sensitive data.
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.
The Digital Operational Resilience Act (DORA) and the TIBER-EU framework work hand in hand to strengthen the cybersecurity and resilience of financial institutions in the EU—DORA sets the regulatory foundation, while TIBER-EU enables realistic, threat-led testing. Together, they promote a proactive approach to identifying and mitigating cyber risks. We spoke with two of our TIBER-experienced experts to explore what makes these tests unique, the challenges they pose, and why elements like social engineering and physical security are key factors.
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.
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.
