Deep Tide TechFlow News, May 20 — Grafana Labs' official blog disclosed that on May 16, 2026, Grafana Labs confirmed it was targeted by a cybercriminal group. The attackers exploited the TanStack npm supply chain vulnerability (Mini Shai-Hulud operation) to infiltrate their GitHub repository on May 11, downloading both public and private source code, internal operational information, and some business contact emails, and subsequently issued a ransom threat.

Grafana Labs stated that the code repository was only downloaded and not tampered with, and that customer production systems and the Grafana Cloud platform were unaffected. They have decided not to pay the ransom and have reported the incident to federal law enforcement. The company has initiated measures such as token rotation, log review, submission audits, and security reinforcement of CI/CD pipelines. A full post-incident report will be published after the investigation concludes.
