At Nucleus Security, our goal has always been to deliver an intuitive and scalable vulnerability management platform. A critical part of this mission is ensuring that its user interface (UI) evolves to meet our customers’ needs. I’m pleased to announce that we recently rolled out an updated UI—an important first step in a series of planned improvements aimed at enhancing our users’ experience with the Nucleus platform.

CVE-2023-2163 is a critical vulnerability in the Linux Kernel, specifically affecting kernel versions 5.4 and above (excluding 6.3). This vulnerability arises from incorrect verifier pruning in the Berkeley Packet Filter (BPF), leading to unsafe code paths being incorrectly marked as safe. The vulnerability has a CVSS v3.1 Base Score of 8.8, indicating its high severity. The consequences are arbitrary read/write in kernel memory, lateral privilege escalation and container escape.

Our users secure products and services developed by dozens of distributed technical teams. They rely on tools like Detectify to prioritize and triage vulnerability findings onward to development teams to remediate. This process is anything but straightforward, which is why we’re excited to see our users utilize our integration platform in ways that help them work efficiently alongside their tech teams.

Large Language Models (LLMs) transform how organizations process and analyze vast amounts of data. However, with their increasing capabilities comes heightened concern about LLM security. The OWASP Top 10 for LLMs offers a guideline to address these risks. Originally designed to identify common vulnerabilities in web applications, OWASP has now extended its focus to AI-driven technologies. This is essential as LLMs are prone to unique LLM vulnerabilities that traditional security measures may overlook.

Recently, AWS expanded the scope of their AWSCompromisedKeyQuarantine policies (v2 and v3) to include new actions. This policy is used by AWS to lock down access keys that they suspect have been compromised. A common example of this process in action is when AWS automatically applies the quarantine policy to any keys found by scanning public GitHub repositories. This proactive protection mechanism can stop compromises before they happen.

Ransomware continues to evolve, and the latest escalation in tactics comes from the Embargo ransomware group. Threat actor Storm-0501, known for its previous ties to various ransomware groups, has now shifted its focus towards hybrid cloud environments, targeting both on-premise and cloud-based systems. This strategic shift poses significant risks for organizations relying on cloud infrastructure, particularly those in critical sectors such as healthcare, government, transportation, and law enforcement.

Work from home (WFH) remains a common practice for many businesses worldwide. This working model has enabled companies to hire top talent across borders, boost revenue, and improve employees work-life balance. A new report by Tata Consultancy Services (TCS) claims that, by 2025, 40% of employees around the world will work from home. However, this growing trend also brings about a range of cybersecurity risks that could impact businesses significantly.

If you wish to fortify your organization’s cybersecurity posture, obtaining a Cyber Essentials certification is a good idea. It enables IT managers to be more aware of the cybersecurity risks in their environment and take actionable steps to mitigate them. Before you pursue it, though, you should decide between two certification levels: Cyber Essentials and Cyber Essentials Plus. ‍ While both are cybersecurity assurance schemes, Cyber Essentials Plus offers a greater level of assurance.

Enterprises are increasingly adopting multi-cloud environments to take advantage of the flexibility and scalability of different cloud platforms. However, this shift has also introduced a major security challenge: the rise of identity-based threats. With 82% of data breaches now involving cloud-stored data, securing cloud identities has become a critical need. The complexity of managing identities and permissions across multiple cloud platforms only amplifies the risks.
