🔍 Cisco researchers found that popular frontier LLMs from OpenAI, Anthropic, Google, xAI, and Amazon exhibit substantially higher risk when subjected to multi-turn adversarial attacks than when assessed with single-prompt safety benchmarks. The team ran tens of thousands of single-turn and multi-turn attacks across 15 models and multiple configurations, revealing wide gaps in attack success rates (ASRs) and configuration-dependent safety behavior. They urge improved benchmarks, transparency on configuration impacts, and publication of paired single- and multi-turn ASRs to better inform procurement and governance decisions.

🧩 Amazon SageMaker Inference now supports OpenAI-compatible APIs, enabling existing tools and frameworks like the OpenAI SDK, LangChain, and Strands Agents to connect directly to SageMaker endpoints. Switching requires only changing an endpoint URL, with no custom integration code or SDK wrappers. You can continue using your current authentication approach while choosing GPU instances, keeping data in your VPC, running open source or fine-tuned models, and leveraging auto-scaling policies. This capability is available today across multiple AWS regions with AWS credentials and automatic token refresh for production use.

🛡️ OpenAI disclosed that two corporate employee devices were compromised by the Mini Shai-Hulud supply chain attack linked to TanStack. The company said no user data, production systems, or intellectual property were accessed or altered, though limited credential material was exfiltrated from a subset of internal source-code repositories. OpenAI isolated affected systems, revoked sessions, rotated credentials and code-signing certificates, and temporarily restricted deployment workflows. macOS users must update affected apps before the June 12, 2026 certificate revocation cutoff.

🔒 OpenAI confirmed that two employee devices were breached in the Mini Shai-Hulud/TanStack supply-chain attack that compromised hundreds of npm and PyPI packages.
