Employees routinely include sensitive data—credentials, trade secrets, customer info—in prompts, risking data leakage and retraining exposure. Prompt injection attacks (both direct and indirect via malicious websites or documents) can manipulate AI agents into revealing system prompts, leaking credentials, or executing unauthorized actions. AI-enabled browsers like Perplexity's Comet and OpenAI's Atlas further expand this attack surface by running autonomous agents with SSO access. Recommended defenses include input validation, output sanitization, threat intelligence for jailbreak patterns, least-privilege principles for AI agents, and comprehensive logging of all agent interactions. Regulatory pressure around AI data privacy is also increasing globally. ## Full article daily.dev links to this article rather than hosting it.
