Chainstack says an AI-powered attack campaign reached its customer account data
See how this story connectsChainstack said an external attacker reached part of its infrastructure through a third-party component, in an incident it says was part of a broader AI-powered attack campaign reported in late October. The attacker entered a development environment on 26 October 2026 and parts of its production environment on 29 October, and accessed a database holding customer account information, which may include organisation names, account holder names, member email addresses and password hashes. Chainstack detected the intrusion on 31 October and cut the access paths the same day; customer nodes, the console and the API were not modified.
Why it matters
Chainstack asks customers to change passwords and rotate node credentials, which it treats as exposed, and to regenerate platform API keys if they use the platform API.
