Industry - Data Breach
Executive Summary
Grafana Labs confirmed a data breach after hackers used a compromised token to access the company's GitHub environment and download its source code. The company stated that no customer data or personal information was accessed, and it declined to pay the ransom demanded by the attackers, a cybercrime group called Coinbase Cartel. Grafana has reset the compromised credentials and is conducting a forensic investigation into the incident.
What Happened
On May 18, 2026, Grafana Labs confirmed that hackers used a compromised authentication token to access the company's GitHub environment and download its source code. The intrusion was claimed by a cybercrime group called Coinbase Cartel, which listed Grafana on its leak website on May 15 and demanded a ransom to prevent the code's release. Grafana declined to pay the ransom, reset the compromised credentials, and launched a forensic investigation into how the token was obtained.
Who Is Affected
Grafana Labs is directly affected through the theft of its proprietary source code. According to the company's statement, no customer data, personal information, or customer systems were compromised during the breach. Grafana's 7,000+ global customers, including major technology companies, are not reported to have experienced direct data exposure from this incident.
Why It Matters
This breach highlights the ongoing threat to software supply chains, where attackers target developer environments and authentication credentials to access valuable intellectual property. The incident involves Coinbase Cartel, a group reportedly linked to prolific cybercrime operations including ShinyHunters, Scattered Spider, and Lapsus$, which have conducted a major data theft campaign against high-profile companies since 2024. The breach demonstrates how even security-focused technology companies remain vulnerable to credential compromise, and Grafana's decision not to pay the ransom aligns with FBI guidance discouraging ransom payments.
What You Should Do
If you are a Grafana customer, monitor communications from the company for updates on the investigation and any potential security recommendations. Review your own organization's access token management practices, including rotation schedules and monitoring for unauthorized use of credentials in developer environments like GitHub. Enable multi-factor authentication on all developer tools and code repositories, and implement logging to detect unusual access patterns to sensitive systems.
