Gemini AI Calendar Exploit Shows Why AI Convenience Needs Vigilance

Security researchers recently revealed how Google’s Gemini AI can be manipulated through a poisoned Google Calendar invite, sending seemingly harmless events that secretly trigger Gemini to control smart home devices. In dramatic demos during Black Hat, researchers prompted Gemini to open shutters, turn on a boiler, and initiate Zoom calls—all via instructions embedded in calendar entries.

Dubbed “Invitation Is All You Need,” the attacks involved 14 indirect prompt-injection exploits capable of taking both digital and physical actions through what appear to be routine interactions. The implications are clear: AI boundaries are porous without human oversight.

Google has responded swiftly, rolling out layered safeguards such as user confirmation prompts and enhanced detection systems. For organisations, this serves as a powerful reminder that integrating AI into workflows demands the same rigorous security controls and oversight you would apply to any other high-risk system.
