The definition of Artificial Intelligence (AI) has been thrown around whilst it has risen to the top of the tech agenda over the past couple of years. Security professionals have determined AI to be a risk to businesses, and also an opportunity. But could it also be a way to better defend your network against attacks? For many years, AI and Machine Learning have gone hand in hand; with AI used to better determine defensive decisions and cut down on the human element in more basic functions.

In Q1 2024, we saw an evolution in techniques used by attackers, some of which may point to longer term trends in the variation and sophistication of attacks faced by organizations. In particular, with regards to phishing, we saw SMS and voice-based tactics being used, which raises concern around the potential for deep fakes and AI-type technologies to further enhance the effectiveness of phishing attacks.

Ongoing social engineering campaign targets enterprises, hackers expand DNS tunneling, and a malvertising campaign leads to ransomware.

Mergers and acquisitions often sound amazing to the Board, but they can become an operational nightmare for the infrastructure, networking, and security teams. In recent years, I’ve worked with a fair few highly acquisitive organisations and so I have seen firsthand that the practical steps to onboard new users can become hugely challenging–especially when the two organisations are running different technologies.

Large Language Models (LLMs) have become indispensable tools across various sectors, reshaping how we interact with data and driving innovation in sensitive domains. Their profound impact extends to areas such as healthcare, finance, and legal frameworks, where the handling of sensitive information demands heightened security measures.

Last week’s release of OpenAI’s GPT-4o, along with the story around Slack’s AI training policy, goes to show that AI innovation is happening at a rate where, for most companies, security simply can’t keep up.

Whether it's because industrial control systems remain quite vulnerable to attacks, or because these systems manage valuable physical resources and uptime is essential—or a bit of both—attackers are increasingly targeting operational technology (OT) and industrial control systems (ICS).

Much has been made of cyber resilience in recent years. And with good reason: failing to bounce back quickly from a security event can have dramatic financial consequences. In early 2023, Royal Mail took several days to recover from a Lockbit cyberattack, losing upwards of £10 million in the process. However, for all the talk about resilience, the industry seems to be overlooking one of its fundamental tenets: risk management. It is, perhaps, understandable that we overlook risk management.

Access control in backend Node.js applications is fundamental to web applications built with the Express web framework. It ensures users can access only the data and functionality they're authorized to use. However, when access control is compromised, users can access data that they shouldn't be able to. This is especially problematic if attackers attempt to manipulate or steal private data.
