A new cybersecurity report by Miggo Security Ltd. exposes a vulnerability in Google LLC’s AI ecosystem, specifically Google Gemini. The flaw allowed attackers to inject natural-language prompts into Google Calendar event descriptions, potentially exfiltrating sensitive data without using malicious code. This attack had three stages: embedding a harmful instruction in a calendar invite, triggering it through routine user questions, and executing it with Gemini’s permissions, thereby creating a new event with private meeting summaries. Although Google has since mitigated this vulnerability, the incident underscores a critical shift in application security, suggesting that current defenses must move beyond simple keyword blocking. Researchers advocate for advanced runtime systems capable of understanding context, intent, and data provenance to safeguard large language models effectively. This situation highlights the evolving need for robust cybersecurity as AI technologies become increasingly integrated into daily business operations.
