Artificial Intelligence (AI) is no longer just a tool we talk to; it is a tool that does things for us. These are called AI Agents. They can send emails, move data, and even manage software on their own. But there is a problem. While these agents make work faster, they also open a new "back door" for hackers. The Problem: "The Invisible Employee" Think of an AI Agent like a new employee who hasView the full article

You can't control when the next critical vulnerability drops. You can control how much of your environment is exposed when it does. The problem is that most teams have more internet-facing exposure than they realise. Intruder's Head of Security digs into why this happens and how teams can manage it deliberately. Time-to-exploit is shrinking The larger and less controlled your attack surface is,View the full article

Organizations typically roll out multi-factor authentication (MFA) and assume stolen passwords are no longer enough to access systems. In Windows environments, that assumption is often wrong. Attackers still compromise networks every day using valid credentials. The issue is not MFA itself, but coverage.
