Chainstack development and production breach exposes customer account information
Impact: Customer account information and node credentials; number of affected customers undisclosed
Chainstack said a cyber-attack in late October 2026 exposed customer account information. The attacker entered the development environment through a third-party component before accessing some production systems and a customer account database. Organisation names, account holder names, email addresses and password hashes may have been exposed, and the company advised rotating credentials, including changing passwords and reissuing API keys, while treating node credentials as exposed as well. The company said the threat had been contained.
