Imagine a customer service representative at your organization uploads sensitive customer data into an AI tool to draft emails more quickly. When an employee uses an AI tool without IT approval, it is known as shadow AI, and such scenarios are becoming increasingly common. Among employees who use AI at work, 78% report using tools that have not been formally approved by their organization, according to Microsoft’s 2024 Work Trend Index.

Data exfiltration is the unauthorized transfer of sensitive data out of an organization's control. It happens across endpoints, cloud applications, removable storage, email, and, increasingly, AI tools. Understanding the most common forms of data exfiltration is the first step toward stopping it.

In conversations with CISOs about their agentic environments, the question I ask first is not whether they have agents deployed. Most do. It is not whether those agents are creating value. Most are. The question I ask is whether they have mapped their Agentic Security Graph. Almost none of them have. And that gap, between the agentic infrastructure that exists inside their organizations and the visibility they have into it, is where the most serious AI security risk in the enterprise lives right now.

Article by Luis Monzon originally published on MyBroadband, May 9, 2026. Anthropic’s AI model Mythos, part of its Claude software, represented a clear threat to banks and financial institutions in South Africa. This is according to Bijan Sanii, CEO of Canadian fraud detection provider INETCO. Anthropic, one of the world’s most important generative AI makers, positioned Mythos as an extremely capable AI model designed to identify vulnerabilities in critical software beyond human capabilities.

In 1996, the US signed the Health Insurance Portability and Accountability Act (HIPAA) into law. One of the government’s chief goals was to safeguard sensitive patient data and protected health information (PHI) from unauthorized disclosure. While these protections were critical, HIPAA compliance requirements (alongside an already-fragmented electronic health record systems) have led to ongoing data silos across healthcare.

As enterprises modernize infrastructure, the shift toward self-service virtualization on Kubernetes is accelerating. Platforms such as Mirantis k0rdent AI and k0rdent Enterprise feature KubeVirt-based virtualization, enabling organizations to deliver on-demand infrastructure while maintaining governance controls.

In July 2025, an AI agent reviewed a support ticket, queried a production database, and leaked integration tokens directly to the attacker watching the thread. Months earlier, another AI followed "hidden instructions" in a public repository, exfiltrating private code into a visible pull request. In both cases, the AI wasn't broken; it simply obeyed the attacker instead of the developer.

Defenders have long known that richer evidence improves security outcomes by enabling faster triage, deeper analysis, and more complete investigation. Although Corelight was founded on this premise, it’s been hard for us to quantify the impact of better network data - until now. Recently, we built an agentic test harness to measure the success of frontier LLMs in responding to real-world attack scenarios, using a range of source data.

43% of businesses in the UK reported a breach last year, with phishing driving the vast majority (85%) of these attacks, the Register reports. A survey by the British government found that attacks involving only phishing grew by six percent in 2025.
