What is HellCat?HellCat is the name of a relatively new ransomware-as-a-service (RaaS) group that first came to prominence in the second half of 2024. Like many other ransomware operations, HellCat breaks into organisations, steals sensitive files, and encrypts computer systems - demanding a ransom payment for a decryption key and to prevent the leaking of stolen files.So it's your typical "double...

What is the VanHelsing ransomware?First reported earlier in March 2025, VanHelsing is a new ransomware-as-a-service operation.Oh, so it's a relatively new player on the malware scene, then. Why the concern?At least three victims of VanHelsing have already been identitified, and a number of variants of the malware have been analysed by security researchers. The fact that VanHelsing runs as a RaaS...

The terms “patch management” and “vulnerability management“ are not the same. And that difference is a big difference.They may be confused because applying patches is one of the many ways to mitigate cyber risks. However, it is one piece of the entire vulnerability management puzzle and organizations that do not realize this are burdened with a false sense of security. A patch management program...

If your website is targeting multiple states or countries, by default, you face a double-pronged challenge: adapting to regional regulatory demands while defending against sophisticated cyber threats. Tackling this requires localization. But what does the term actually entail?Localization isn’t just about tailoring products, services, and infrastructure to meet local market requirements; it has...

A critical aspect of manufacturing, energy, and transportation is Industrial Control Systems (ICS) and Operational Technologies (OT). The rapid pace of digital growth makes these systems susceptible to cyberattacks.OT and ICS system security is important, making penetration testing an essential activity. This tactic makes it possible to mitigate weaknesses so they are no longer vulnerabilities. It...

Tripwire's February 2025 Patch Priority Index (PPI) brings together important vulnerabilities for Microsoft.Up first on the list are patches for Microsoft Edge (Chromium-based) that resolve 4 remote code execution and 2 spoofing vulnerabilities.Next on the list are patches for Microsoft Office and Excel. These patches resolve 8 issues such as remote code execution and information disclosure...

The evolution of the cyber threat landscape highlights the need for organizations to strengthen their ability to identify, analyze, and evaluate cyber risks before they evolve into security incidents. Criminals often exploit known unpatched vulnerabilities to penetrate Industrial Control Systems (ICS) environments and disrupt critical operations. Although patch management seems like the obvious...

Many organizations have a vulnerability management (VM) problem without knowing it. Vulnerability management is a crucial component of any organization’s cybersecurity program and is required by most major compliance standards because of its sink-or-swim impact on network security. One of the biggest issues in VM is that organizations aren’t testing the entirety of their networks. Could yours be...

The original NIS Directive came into force in 2016 as the EU’s first comprehensive law governing cybersecurity in member states. As part of its key policy objective to make Europe “fit for the digital age,” the European Commission proposed in December 2020 that NIS be revised, and NIS2 entered into force in January of 2023. Member states were required to transpose it into law by October 17, 2024...

Security experts have warned that a cybercriminal group has been running a malicious and inventive phishing campaign since August 2024 to break into organizations across Europe, North America, Africa, and the Middle East.The Russian group, known as Storm-2372, has targeted government and non-governmental organisations (NGOs), as well as firms working in IT, defence, telecoms, health, and the...

Today’s VERT Alert addresses Microsoft’s February 2025 Security Updates. VERT is actively working on coverage for these vulnerabilities and expects to ship ASPL-1143 as soon as coverage is completed. In-The-Wild & Disclosed CVEsCVE-2025-21391A vulnerability in Windows Storage could lead to elevation of privilege, however, it is important to note that this would not give complete access to the file...

Building a vulnerability management (VM) program from the ground up is no small feat. It requires technical expertise, organizational buy-in, and a clear roadmap. In recent months, I’ve been working with a client who had to discard their legacy approach and start afresh. We came to realize just how many components have to come together to get a decent start on a VM project while also showing value...

Tripwire's January 2025 Patch Priority Index (PPI) brings together important vulnerabilities for Microsoft.First on the list are patches for the Microsoft office platform, including Word, Access, Visio, Excel, OneNote, and Outlook. These patches resolve 13 issues such as remote code execution and security feature bypass vulnerabilities.Next are patches that affect components of the core Windows...

Recently, I looked at Microsoft’s assigned CVSS v3.1 scores for Patch Tuesday vulnerabilities alongside the Microsoft assigned severity ratings. I wanted to revisit these numbers and see just how closely CVSS aligns with Microsoft’s opinion of severity.Disclaimer: I’m aware that CVSS v4.0 exists. However, Microsoft has not yet adopted it, and I wanted an apples-to-apples comparison.What Is CVSS v3...

The energy sector is the cornerstone of modern infrastructure, powering essential services and supporting the daily operations of economies worldwide. However, it also faces unique cybersecurity challenges, particularly in complying with the North American Electric Reliability Corporation's Critical Infrastructure Protection (NERC CIP) standards.Cyber threats keep growing in sophistication and...

Remote work isn’t just a temporary trend anymore; it has become a permanent fixture. What began as a quick response during the pandemic has evolved into the new normal for businesses worldwide. In America, 20% of people now work from home.While this has its advantages (flexibility for workers and cost savings for businesses), it’s not without its complications, having cracked open a host of issues...

Enterprise networks frequently experience changes in endpoint devices, software, and files, which can introduce risk to the organization. To mitigate this, companies can implement foundational security controls like file integrity monitoring (FIM), which tracks changes to essential files and helps restore them if unauthorized. Additionally, organizations may use these controls to monitor for...
