Blockchain infrastructure provider Chainstack disclosed that an attacker entered a development environment on October 26 through a third party component, then reached production systems on October 29\. Customer password hashes were exposed.

Chainstack says customer nodes, the console and the API were not modified, and payment card details were not stored, so they were not exposed. The company asked customers to rotate node credentials. The Hacker News reports overlaps with a China linked campaign that uses ARTEX, an autonomous AI penetration testing framework, though the link is not confirmed by Chainstack itself.
