Cybersecurity

Copilot Data Exposure Risk

Security researchers at Lasso discovered that Microsoft Copilot can access data from over 20,000 GitHub repositories even after they've been made private. This issue affects over 16,000 organizations, including Amazon, Google, IBM, PayPal, Tencent, and Microsoft. The problem arises from Bing's caching mechanism, which indexes data and makes it accessible via Copilot even after the source is secured. The chatbot could return confidential GitHub archives containing intellectual property, sensitive corporate data, access keys, and tokens. Lasso advises affected companies to rotate or revoke any compromised keys.
