Your AI Copilot Is the Newest Attack Surface

Four distinct security incidents in early 2026 prove that AI assistants have become viable, weaponizable attack vectors. Researchers demonstrated zero-click data exfiltration through Excel's Copilot Agent, full system compromise via Chrome's Gemini panel, session hijacking of Microsoft Copilot Personal, and 1Password vault takeover through Perplexity's agentic browser. Each exploits the same fundamental problem: AI agents inherit broad permissions and cannot reliably distinguish legitimate instructions from attacker-controlled content. The industry data confirms the gap: 83% of organizations plan to deploy agentic AI, but only 29% feel ready to secure it.
