**Hacker Pranks Exclusive: Agent Security is Just Security**

In recent times, the term "agent security" has been gaining traction in cybersecurity circles. However, Colin Walters' blog post on the topic raises some crucial questions about whether we're reinventing the wheel. As it turns out, agent security is not as revolutionary as it's made out to be.

The concept of Landlock, a Linux security tool, has been popping up more frequently in discussions around agent security. However, this is not surprising given its obscurity until now. Landlock is a useful tool for isolating applications and preventing privilege escalation attacks, but it's not the silver bullet some proponents claim it to be.

**The Problem with Agents: Arbitrary Code Execution**

One of the main issues with agents like OpenCode, Claude Code, Cursor, and OpenClaw is that they often provide arbitrary code execution as a feature. This means that these tools can execute any code on your system without restrictions, which is a recipe for disaster. Even more concerning is the trend of giving LLM (Large Language Model) tools blanket read and write access to user accounts, which poses significant security risks.

**The Dangers of Prompt Injection**

As we've seen in various examples, prompt injection can be particularly damaging when dealing with sensitive information. Giving an LLM tool unrestricted access to your browser cookies or files can lead to catastrophic consequences. It's essential for users to understand these risks and take necessary precautions when using LLM tools.

**The Solution: Containerization and Isolation**

So, what's the solution? Colin Walters suggests that we should be using containerization and isolation techniques instead of relying on new "next-generation" security solutions. Technologies like Docker, Flatpak, and Kubernetes have been around for years and provide robust isolation capabilities. By leveraging these tools, we can prevent privilege escalation attacks and ensure that agents don't have unfettered access to our systems.

**Landlock: A Complementary Tool**

While Landlock is a valuable tool, it's not a replacement for other sandboxing techniques. Its primary use case is as a complement to coarse-grained isolation techniques like virtualization or containers. In some cases, using Landlock can help an application further isolate itself from the host system.

**The Credential Problem**

One area where new tooling may be necessary is in addressing the credential problem specific to agentic AI. Traditional containerized applications often use relatively static credentials, whereas developer/user agentic AI requires more dynamic and freeform access. This makes it easier for attackers to inject credentials via prompt injection.

**Conclusion**

In conclusion, agent security is not as revolutionary as some proponents claim. We don't need to reinvent the wheel; instead, we should build on top of existing technologies like containerization and isolation. By leveraging these tools, we can prevent privilege escalation attacks and ensure that agents don't have unfettered access to our systems. As Colin Walters aptly puts it, "agent security is just security." Let's not forget this crucial lesson when exploring new security solutions.

**Takeaway: Don't Wire Up LLMs Without Sandboxing**

In the end, one takeaway from this discussion stands out: don't wire up an LLM via OpenShell or a similar tool to your complete digital life without sandboxing. This is a recipe for disaster, and we've seen it happen before.
