Email AI Assistant

An email AI assistant is a software tool that uses artificial intelligence to help users manage, compose, and respond to email communications with minimal manual effort. These systems can automatically draft messages, summarize lengthy email threads, flag priority items, and suggest appropriate responses, which raises important governance questions around data privacy, model transparency, and employee monitoring. Organizations deploying email AI assistants must establish clear policies governing how training data is handled, what employee communications can be processed, and how to maintain confidentiality of sensitive business information.

Email AI Assistants Can Be Weaponized to Steal $250K and Suppress Audit Logs

Barracuda Networks researchers demonstrated a proof-of-concept attack in which a compromised email account's built-in AI assistant is turned against the enterprise, suppressing audit logs, conducting internal reconnaissance, and ultimately redirecting a $250,000 wire transfer. The attack uses only the AI tool's existing legitimate permissions, making it invisible to standard behavioral monitoring. Traditional compensating controls including MFA and email authentication did not prevent the attack chain.
