Microsoft has fixed a vulnerability in its Copilot AI assistant that allowed hackers to pluck a host of sensitive user data with a single click on a URL. The hackers in this case were white-hat researchers from security firm Varonis. The net effect of their multistage attack was that …

There’s a well-worn pattern in the development of AI chatbots. Researchers discover a vulnerability and exploit it to do something bad. The platform introduces a guardrail that stops the attack from working. Then, researchers devise a simple tweak that once again imperils chatbot users. The reason more often …

The face-palm-worthy prompt injections against AI assistants continue. Today’s installment hits OpenAI’s Deep Research agent. Researchers recently devised an attack that plucked confidential information out of a user’s Gmail inbox and sent it to an attacker-controlled web server, with no interaction required on the part of …

Researchers needed less than 48 hours with Google’s new Gemini CLI coding agent to devise an exploit that made a default configuration of the tool surreptitiously exfiltrate sensitive data to an attacker-controlled server. Gemini CLI is a free, open-source AI tool that works in the terminal environment to …

Imagine a world where AI-powered bots can buy or sell cryptocurrency, make investments, and execute software-defined contracts at the blink of an eye, depending on minute-to-minute currency prices, breaking news, or other market-moving events. Then imagine an adversary causing the bot to redirect payments to an account they control …

In the growing canon of AI security, the indirect prompt injection has emerged as the most powerful means for attackers to hack large language models such as OpenAI’s GPT-3 and GPT-4 or Microsoft’s Copilot. By exploiting a model's inability to distinguish between, on the one hand, developer-defined …
