Chainstack has urged customers to replace node credentials and update their applications after a data breach, while saying its blockchain infrastructure services stayed online.

Customers are being asked to replace the node credentials and update their applications to reflect the change. Chainstack presented both tasks as part of its response for customers. The request covers both credential rotation and application updates.

Chainstack said its services remained online. The service remained online while Chainstack asked customers to change their credentials and applications. Its infrastructure services continued to be available while the provider asked customers to take those steps.

The breach prompted Chainstack to ask customers to make both changes. For users of its blockchain infrastructure, the immediate instruction is to replace node credentials and update applications. The company's two central points are that customer configurations should be changed and that its services stayed online.
