Grafana Labs has confirmed a security breach where attackers used a stolen token to access its GitLab environment, obtaining source code repositories. The company assured that customer records and financial data were not compromised. Despite the hackers' attempt to extort the company by threatening to expose the codebase, Grafana Labs refused to pay the ransom. The breach involved a token with permissions to access the GitLab environment, which has since been revoked. Grafana Labs has implemented additional security measures to prevent future incidents. While the company's core code is open source, it remains unclear if any unpublished proprietary code was accessed. The company has not provided further clarification on this matter.
