I've been working on something similar , policy guardrails for coding agents, with OPA backed policies and os-native sandbox - https://github.com/LuD1161/agentjail

I just checked the repo. Nice work A suggestion: 1. Adding which repo/project was where my most tokens were consumed. I checked the image in the repo README, didn't see that graph.

Hey thanks for the question. I would like to answer it in a more descriptive manner with an example later.

Classifying a command can be a bit of a misnomer because it has two inherent problems:

1. You need a classifier. That means the security boundary becomes “can I trick or bypass the classifier?” Whether it is a smaller model or a pile of regexes, it will eventually have edge cases.

2. The token economics do not work, and it also needs to be fast. I do not want an eval evaluating another eval for every command.

So the approach I took is closer to how we normally build security systems: secure defaults and deterministic boundaries.

For example, to protect secrets, AgentJail can block access to paths like `~/.ssh`, `~/.aws/credentials`, `.env`, etc. at the OS level.

The OS is the deterministic boundary here. The ring-0 enforcement layer.

The more interesting problem is network access. You may genuinely want the agent to debug a production Kubernetes cluster, inspect an AWS resource, or query a production database. A blanket network deny would make the agent useless.

For that, I am taking a protocol-aware DSL approach. Something like:

``` deny if { request.host == "api.github.com" request.method == "POST" startswith(request.path, "/repos/") endswith(request.path, "/git/refs") }

ask if { request.host == "kubernetes.default.svc" request.method == "DELETE" }

allow if { request.host == "api.github.com" request.method == "GET" } ```

So instead of trying to classify whether a command is “dangerous,” the policy describes exactly which resources and operations are allowed, denied, or require approval.

The agent can still be probabilistic. The enforcement boundary should not be.

Does that answer to your question?

You mean, I should stop posting much about it ? Is it too aggressive posting Am sorry about that.

With agentjail ( https://github.com/LuD1161/agentjail ), I've tried to contain coding agents in os-native sandboxes (sbpl for macos and similarly for linux, <4ms start time) + policy guardrails evaluated by Open Policy Agent (OPA), policies written in rego.

Protocol aware network proxy coming soon Then you can match a DSL and block particular network requests.

This ensures you no longer fear --dangerously-skip-permissions and stop babysitting agents

What else would you want to see in this project? Please star the repo, if you like the idea :)

Policy guardrails for Coding Agents. Never babysit your agents - github.com/lud1161/agentjail

· OS native sandbox (<4ms start-time) · Policies for AWS, local files, k8s, DBs etc. · Rego backed policies w/ OPA (CNCF Graduated project) · Fastest policy evaluator (<3ms)

Please star the repo if you like the work.

Might wanna check out https://github.com/LuD1161/agentjail - policy guardrails for coding agents.

shameless self-plug. I've been dogfooding it for the last 3 weeks now.

Dont trust your production data with a markdown file. Have deterministic guardrails

Thanks !

For now I am parsing the text only. Testing app for real instances would be fun and a dedicated project in itself. I've some ideas, hit me up if you're interested or can collab if you're doing it already.

wow. this is such an interesting perspective. hadn't thought so deeply about my 'shower thought'. This expands my horizon. Might put this into the update. When I was thinking about it, the fleeting thought was majorly about the 'newness effect' which isn't related to a subjective liking of something but is pervasive across everything, whether it be tech, music, movies etc.

Thanks for sharing this.

A friend said KubeCon "isn't the same anymore." I asked what got worse. They couldn't answer. Turns out there's a name for this.

Three names, actually: 1. Hedonic Adaptation : Brain's inbuilt boredom machine 2. Rosy Retrospection : Your Memory is a Highlight Reel 3. Declinism : The "Kids These Days" Bias

I found an Insecure Direct Object Reference(IDOR0 security issue that led to leaking GST challans (receipts) of all the 11.8M registered taxpayers. Here's the full story alongwith a video PoC.

Note: No personal data was ever shared or harvested. This was responsibly disclosed to the authorities through proper channels and only after the disclosure timeline (120 days) was it published in the online media.

I've started this series on online privacy to teach people some of the good online cybersecurity hygiene, that can help them keep safe.

This is my first attempt at recreating a bug from its test case, feedback is highly appreciated.

Not expected this from a security company :P Please fix/update your certs :)

In this blog we will see a step-by-step guide of what goes behind a successful pentest. This not only includes the technical aspects but also the business and legal aspects of it.

If you’re tasked with the responsibility for getting your organisation's app or website's pentest done, this blog would definitely help you navigate the waters easily.

Thanks everyone for the warm reception of the first episode of the series Be The H.A.C.R.

Here Comes the second :

Files Leaking Sensitive Info - Be The H.A.C.R. - Ep - 02

HackThisSite - Basic Missions 2 & 3

This episode includes 1. Twitter Info leak - $560 awarded 2. Yahoo info leak - 2 phpinfo pages 3. Boozt info leak. - $60 awarded

Thanks for your feedback. Have done some major improvements regarding the video and audio quality.

Please check this out and give your feedback :)

Just started with my YouTube channel : HackingSimplified Hope to get some feedback here. P.S. There's a feedback link in the end ( as well as in the description ).

A few improvements I got in early feedback :

1. Improve on video quality ( doesn't look 1080p )

2. Improve on sound quality

3. Please please decrease jump cuts or at least make them smooth

4. Decrease your screen time : Don't want to see you so much -_-

Have started working on next video, current setup has serious hardware constraints ( recording audio and video from phone ) and lockdown has increased difficulty getting better hardware.

Nevertheless would love to hear your opinions on this. Also let me know what all needs to be improved on technical aspects.

Hi! It's my first blogpost this year. It's about how a huge travel portal's customer PII data could've leaked through some remanant functionality. This led me to discover a few IDORs.

Thanks.
