Security & Safety
1. Show HN: We built free adversarial security testing for agents (OpenClaw too)
Hey everyone — I'm Aaron, co-founder of ZioSec. Wanted to introduce what we've been working on and get your feedback.Quick background: we build adversarial testing software for AI agents — think automated red teaming. We've been building with design partnerships in the Mag 7, Big 4, and red team ...

2. Claude Code Flaws Allow Remote Code Execution and API Key Exfiltration
Cybersecurity researchers have disclosed multiple security vulnerabilities in Anthropic's Claude Code, an artificial intelligence (AI)-powered coding assistant, that could result in remote code execution and theft of API credentials. "The vulnerabilities exploit various configuration mechanisms, ...

5. Bayesian Generative Adversarial Networks via Gaussian Approximation for Tabular Data Synthesis
arXiv:2602.21948v1 Announce Type: new Abstract: Generative Adversarial Networks (GAN) have been used in many studies to synthesise mixed tabular data. Conditional tabular GAN (CTGAN) have been the most popular variant but struggle to effectively navigate the risk-utility trade-off. Bayesian GAN ...

6. Adversarial Intent is a Latent Variable: Stateful Trust Inference for Securing Multimodal Agentic RAG
arXiv:2602.21447v1 Announce Type: cross Abstract: Current stateless defences for multimodal agentic RAG fail to detect adversarial strategies that distribute malicious semantics across retrieval, planning, and generation components. We formulate this security challenge as a Partially Observable ...

8. Show HN: BreakMyAgent – Open-source red-teaming sandbox for LLM system prompts
As a developer, I got tired of manually testing my AI agents and chatbots against the same prompt injections and jailbreaks every time I tweaked a system prompt. Our QA team was struggling with the exact same bottleneck, so I built BreakMyAgent.It’s an open-source sandbox that runs an automated b...
