Chainstack Reports Production Systems Breach Exposing Customer Data and Password Hashes

AI-summarised brief · reviewed before publication

Chainstack, a blockchain infrastructure provider, announced on Tuesday that an attacker accessed its systems through a third‑party component, part of an AI‑powered campaign identified last week. The intruder entered a development environment on Oct. 26, 2026, escalated to portions of the production environment, and was detected on Oct. 31, when the company cut off access and began hardening defenses. The breach exposed a database containing customer organization names, account holder names, member email addresses and password hashes, as well as node‑credential systems, which are now treated as compromised. Chainstack urged customers to rotate node credentials, regenerate API keys, change passwords and watch for phishing. The attack mirrors a China‑linked ARTEX operation that has hit WorkOS, Chainalysis and Dutch Institute for Vulnerability Disclosure.
