Cisco’s latest security sweep has found that many of the most widely used open-weight large language models are alarmingly easy to manipulate with a small series of crafted prompts — and multi-turn (conversation) attacks are the most effective vector, producing success rates two to ten times...

Microsoft has pushed a meaningful new enforcement point into AI agent workflows: Copilot Studio now supports near‑real‑time runtime monitoring that lets organizations route an agent’s planned actions to an external policy engine — such as Microsoft Defender, a third‑party XDR, or a custom...

Microsoft’s Copilot Studio has moved from built‑in guardrails to active, near‑real‑time intervention: organizations can now route an agent’s planned actions to external monitors that approve or block those actions while the agent is executing, enabling step‑level enforcement that ties existing...

In January, security researchers at Aim Labs disclosed a zero-click prompt‑injection flaw in Microsoft 365 Copilot that demonstrated how a GenAI assistant with broad document access could be tricked into exfiltrating sensitive corporate data without any user interaction—an attack class that...

Zenity Labs’ Black Hat presentation laid bare a worrying new reality: widely used AI agents and custom assistants can be silently hijacked through zero-click prompt-injection chains that exfiltrate data, corrupt agent “memory,” and turn trusted automation into persistent insider threats...

Microsoft has announced a significant enhancement to its Azure AI Foundry platform by introducing a safety ranking system for AI models. This initiative aims to assist developers in making informed decisions by evaluating models not only on performance metrics but also on safety considerations...

In a rapidly evolving digital landscape where artificial intelligence stands as both gatekeeper and innovator, a newly uncovered vulnerability has sent shockwaves through the cybersecurity community. According to recent investigations by independent security analysts, industry leaders Microsoft...
