Focus on Cyber Insurance: How Quantifying Risk Is Reshaping Security

In this latest installment of the Reporters' Notebook video series, we discuss how cyber insurance is forcing organizations to quantify risk, what's covered (and what's not), and why this could be the best thing to happen to cybersecurity.

New AI Usage Report: Enterprise AI Risk Is Heavily Concentrated Among a Small Group of AI "Power users"

State of AI Usage Report 2026 (full report here) by LayerX Security reveals the extent of the enterprise AI visibility gap and why most organizations still don't understand where their AI exposure is actually coming from. The research shows that enterprise AI risk is not distributed evenly across users or platforms. Instead, it is heavily concentrated among a small group of AI power users and a

Reconstructing an Akira Ransomware Kill Chain from Perimeter and Endpoint Logs, (Wed, May 27th)

Most Akira write-ups focus on the ransom note or the encryption routine. By the time those show up the interesting forensic work is over. The questions that matter to defenders sit earlier. How did they get in. When did they get domain admin. What did they touch before the binary fired. Those answers live in the days before impact. They sit in two log sources that almost never get joined. The perimeter firewall and the Windows event channel.

3 SOC Steps that Shut Down Incident Risks Early

Most organizations still picture cyber defense as a fortress problem: build stronger walls, add more guards, buy another detection engine. But modern incidents rarely crash through the front gate. They drift in disguised as routine activity, hide inside legitimate processes, and quietly accumulate risk long before anyone labels them an "incident." That changes the role of the SOC entirely. The

5 Steps to Managing Shadow AI Tools Without Slowing Down Employees

When an employee installs an AI writing assistant, connects a coding copilot to their IDE, or starts summarizing meetings with a new browser tool, they are doing exactly what a productive employee should do: finding faster ways to work. Across most organizations today, employees are running three to five AI tools on any given day. Most were never reviewed by IT. A significant portion connects

Gitea Vulnerability Exposes Private Container Images without Authentication
