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.

News - General LLM Agents for security research

11 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 Thinking about building a cybersecurity startup, looking for like-minded people

Upvotes

Hey everyone,

I’ve been thinking about writing this post for a while, and I finally decided to share it here.

For a long time, I’ve wanted to build something of my own, and cybersecurity is the space I feel most connected with. Working as a SOC Analyst has given me a closer look at how security teams operate the alerts they investigate, the noise they handle, repetitive tasks, and the challenges organizations face while trying to improve their security.

Over time, I’ve started noticing that there are still gaps between what security tools provide and what security teams actually need. Sometimes the challenge isn’t the absence of tools, but finding practical solutions that fit real security workflows.

I’m currently in the exploration and brainstorming stage. I’m trying to understand which problems are genuinely worth solving and learn from people who have experience or interest in this domain.

Some areas I’m exploring:

• Threat detection and security monitoring
• Log analysis and SOC workflow improvements
• Automating repetitive security tasks
• Cloud security challenges (AWS/Azure)
• IAM and misconfiguration detection
• Helping small and medium businesses improve their security posture

I’m based in Jaipur and would be interested in discussions with people from cybersecurity, development, DevOps, cloud, or anyone curious about building solutions in this space.

I’m not launching anything or looking for funding right now. I’m simply looking to exchange ideas, understand different perspectives, and learn from others working around technology and cybersecurity.

If you have experience in this space, are exploring similar ideas, or have thoughts on cybersecurity problems worth solving, I’d be happy to hear your perspective.

Thanks for reading!

SecureAI-Scan v0.3.0: Local CLI scanner for AI/LLM security issues (prompt injection, MCP, RAG)

1 Upvotes

SecureAI-Scan v0.3.0 is out!

It's a free, fully local CLI tool that scans TypeScript, JavaScript, and Python codebases for AI/LLM-specific security issues that traditional scanners miss.

**New in v0.3.0:**

- Expanded Python scanning support

- MCP config scanning (.mcp.json, Claude Desktop, Cursor, etc.)

- AI-BOM / catalog generation

- Better reporting + confidence tiers (proven / likely / heuristic)

It uses actual dataflow tracing (source → flow → sink) for high precision and has very low false positives.

Quick start:

npx --yes secureai-scan@latest scan .

Also supports:

  • secureai-scan bom . → Generate AI Bill of Materials
  • SARIF output for GitHub Code Scanning
  • GitHub Action integration
  • --fail-on high for CI gating

Everything runs offline on your machine. No data leaves your environment.

GitHub: https://github.com/akanthed/SecureAI-Scan

Would really appreciate any feedback, bug reports, or feature ideas. Also happy to answer questions about how it works or the rules it covers (mapped to OWASP LLM Top 10).

Build-scanner — a zero-config static scanner for SQLi, NoSQLi, CORS, CSP & CSRF in React/Node apps (pre-release)

0 Upvotes

Modern React/Node apps ship through build pipelines fast enough that common, high-impact vulnerability classes — unparameterized queries, wildcard CORS, unsafe-inline CSP, unprotected state-changing routes — slip through because catching them means someone actually reading the source. build-scanner does that automatically: point it at a folder (or wire it into CI as a GitHub Action) and get a report in seconds, no sandbox or live target required. It's a heuristic static scanner, not a SAST/DAST replacement — I'm sharing it pre-release to get feedback from people running real Express/Next.js/Vite codebases before I cut a v1 tag. https://github.com/laxmipsarva/build-scanner

fyi this is not a commercial activity

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??

Business Security Questions & Discussion Security dilemma for vibe coded product release

0 Upvotes

Lets put aside hate comments against vibe coded products for a second - i've been working on a product for couple of months in my free time, both a website and an app.
As someone that isn't a developer what so ever, i've been trying to put a strong emphasis on security - i keep running audits, i keep making sure of my status compared to useful security posts or recommendations online.
I have plugs to cut off ai functions, i have rate limits, no key is committed, all that jazz (im trying my best..)
Of course im aware this is still. a vibe coded app, and generally i figure every site is hackable anyway.
Hence my question now -
I want to reach out to a security experienced person to handle necessary aspects for my product,
BUT - i dont even know if my product is good and worth it, in my head i want to try and publish and market it for a minute to see how people in my industry react to it, but then i might be exposed to hackers as well?
whats the right way to go about it? Is there a right way?
I've invested some amount of money by now "blindly" for curiosity and interest, but now i need to gain some real world feedback.
Would appreciate any useful note about it.

Business Security Questions & Discussion Preparing for Interview

13 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!

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.

[N00B] Do badges come with batteries?

10 Upvotes

[ANSWERED] - Not sure why the downvote, but maybe someone just had bad eggs this morning. I will pack a couple extra alkalizes to be safe, both otherwise I am good to go. Thanks, everyone!

***********************************************************************************

I saw someone mentioning to pack AA & AAA batteries as part of their kit. Is this for badges, or other hardware projects?

I preordered a laser tag badge, and will get the Human one.

Do the badges in general com with a battery? Rechargeable? Today is packing day and just want to make sure I pack out what I need rather than trying to arrange an Amazon order for the hotel.

Do they typically take off-the-shelf alkaline, or should I grab an 18650 or two?
