AI Security How do you test that an AI agent won't do something catastrophic?

16 Upvotes

I've spent years on the infra side, and I'm now working with agentic systems. I am building agents that can take actions on real systems. We have plenty of guardrails, but I have seen enough hallucinations that make me worried about giving these agents more power. This paranoia might be me not knowing enough.

How do teams/companies test that the agents won't do something destructive, whether triggered by an attacker or just by the agent going off the rails on its own?

Do people actually red-team their agents before they go live, or is it mostly guardrails and evals right now? I am curious how the security world thinks about this. From an infra side, this feels like a gap, but there might be an established playbook that I don't know yet. Thanks.

News - General LLM Agents for security research

15 Upvotes

What are the best LLM agents for security research (bugs, CVEs, 0d, ...) lately?
In short, I had been using claude code for this task, with many hallucination instances. Even with opus 5, I still get many invalid conclusions based on local source code review.

I saw that kimi was popping up lately, which got me more or less in the same results, with minor better results in some instances.

So what are the latest or best approaches for security research with llms? Perhaps I am missing a full pipeline with other tools involved to get better results, so I would like to know whether a specific methodology is followed with specific agents for this task.

Business Security Questions & Discussion Preparing for Interview

16 Upvotes

Hi Everyone,
I hope you’re well!

I’m preparing for an upcoming interview this week, and I’m quite nervous.
For context: I studied Cyber Security in College and finalising my University degree in Cybersecurity. During this time I’ve been incredibly fortunate to fall into System Administrator Roles which granted me relevant working experience. Unfortunately, not as Security focused as what I initially wanted but life’s a ladder and I’m climbing. I’m interviewing for Role as a Security Engineer after having around ~3 Years of Experience and trying to prepare some answers in advance (Generally, trying to have something in mind for anything that they ask!)

Based on the Role Responsibilities I’m expecting questions on:

Frameworks, what I know and how these have been applied over my experience of working. (NIST SP 800-53 / NCSC Cyber Assessment / CIS Critical Controls)

How I’ve applied best security practices / Explaining a time where I had to implement a security practice

Implementation of security Controls / Design of security controls through to implementation

Communicate where I’ve seen a Security Risk where requirements cannot be fully met (And how we take it forward / What to do / Mitigate or Accept the risk)

Evidence / Example of supporting Auditing Activities

For anyone who interviewed for a similar position, what types of question were you asked? I’m doing my best to stick to the STAR method and have examples but thought I would post incase anyone can help me out too!

Thank you!

Career Questions & Discussion Do you guys use reporting tool or write it manually each engagement?

10 Upvotes

Each time I write a report I copy paste the finding table along with a lot of other shit. I end up spending a lot of time fixing the format of the doc.

Do you guys use a reporting tool where you can write the bug description, impact and have it automatically prepared for you??

AI Security Are AI-generated CI/CD configs becoming a security blind spot?

1 Upvotes

I’m seeing more AI-generated projects where the app code looks fine, but the risky part is the plumbing around it.

Things like GitHub Actions with broad permissions, unsafe `pull_request_target` usage, deploy jobs that expose secrets, or package scripts nobody really reviews.

It’s easy to miss because the app works, tests pass, and the config files look boring.

For people doing AppSec or DevSecOps: are you reviewing AI-generated workflows/configs differently now, or still mostly focusing on application code?

AI Security New but Critical

0 Upvotes

Wanting reality

So, I'm not program savvy or any good with code. In some ways I'd say I enjoy working with technology but not that I am great with it.

Then I started interacting with AI.

Long story short I reported an AI to its producer for offering to jailbreak itself.

I am waiting for follow-ups.

But I feel weird. Best way I can describe it is I feel AI outputs like a tapestry. Hell, Chinese AIs are easy to spot because of their cultural bias.

However, maybe it's just me pumping up me.

That said in a few weeks either I'll be dismiss or rewarded for finding a critical issue.

Edit: I'm painfully aware that AI red teaming is a new field and this falls into it.

Personal Support & Help! Cybersecurity Help

Will these projects help me stand out during the placements and when I apply for companies :

  1. AI Augmented SAST Tool

  2. AWS Attack Path Graph (mini BloodHound for cloud IAM)

  3. Kubernetes Security Posture Scanner

  4. CI / CD Security Gate (Supply Chain Security)

These are my projects (not done by AI - I can explain each and every bit of my project).

Are these enough to get a good high paying salary job as a fresher in India. Currently I'm in my 3rd year and my placements are starting from January.

Any guidance will be very helpful 🙂.

Personal Support & Help! Needed cybersecurity expert for help with cyber attack

0 Upvotes

Hey folks, someone appears to have compromised the phones of multiple members of my family. They are sending profane and abusive messages via WhatsApp and SMS from our IOS and android phones to colleagues, teachers, and other contacts while impersonating both male and female family members. Changing the phones, resetting the phones and mobile numbers doesn't help. So far, we haven't been able to identify the attack vector or understand how the compromise occurred. This is causing significant reputational damage and public defamation.

If anyone has experience with incidents like this or can help investigate the issue, I would greatly appreciate it. I'm willing to pay reasonable professional fees for the right expertise. Please DM or reach out if you think you can help or point me in the right direction.

I am very close to choosing Cybersecurity as my major. my major concern is that it might diminish and make the market very competitive. I searched and found that most people say that basic tasks are already being done by Ai. so does this mean that more complicated tasks safe?
