Grafana Labs, the company behind the open-source analytics and visualization web application of the same name, has confirmed it suffered a data breach.

The hackers have threatened to release the company’s codebase, but Grafana Labs says it won’t be paying any ransom.

It’s a contrast to the recent Instructure breach, in which the company did pay out the ransom for the return of their data. However, it’s also unclear just how much of Grafana Labs’ proprietary information the hackers stole.

In a series of social media posts covered by TechCrunch, Grafana Labs revealed that its team “recently discovered that an unauthorized party obtained a token with access to the Grafana Labs GitHub environment, enabling the threat actor to download our codebase.”

The impact could have been worse, according to the company’s internal investigation.

No customer data or personal information was accessed, and there’s “no evidence of impact to customer systems or operations,” according to the company.

How dangerous is a compromise to Grafana Labs’ open-source observability platform?

The potential scope of the impact could be large — major Grafana Labs customers include Anthropic, Microsoft, and Nvidia, among many more, and the software has a total of more than 25 million users worldwide.

Granted, the software is open-source: Anyone can download the public code and modify it themselves. While the hackers may have stolen proprietary information — perhaps source code for Grafana Cloud or enterprise solutions — the company hasn’t revealed more specifics about the incident.

Grafana Labs’ investigation is still ongoing, but it says it has shored up the security issues that led to this particular breach: They have “invalidated the compromised credentials and implemented additional security measures to further secure our environment against unauthorized access.”

“As part of Grafana Labs’ standard security practices, we will share additional information from our post-incident review when our investigations are complete,” the company explained in their statement.

In 2026, keeping your codebase safe is tougher than ever. This month alone, Google has confirmed the first known case of a hacker group developing a zero-day exploit specifically through the use of AI tools.
