The emergence of Echoleak signifies a new trend in cybersecurity, where AI assistants, such as Microsoft 365 Copilot, can be manipulated through crafted text prompts. Research from Check Point indicates that these zero-click attacks leverage language as a weapon, bypassing traditional malware and phishing methods. This highlights a concerning vulnerability: AI systems, designed for user assistance, can unintentionally act on malicious instructions. As attackers exploit the obedient nature of LLM-based assistants, this shift from code to conversational attacks reshapes the landscape of cybersecurity, challenging existing protective measures.
Copilot did exactly what it was designed to do: help. Only the instruction came from an attacker, not the user.
The attack vector has shifted from code to conversation. We have built systems that actively convert language into actions. That changes everything.
