Chainstack disclosed that it suffered an AI-driven cyber attack at the end of October, resulting in the exposure of customer account information

Blockchain infrastructure service provider Chainstack disclosed that it experienced an AI-driven cyber attack from October 26 to 31, 2026. The attacker accessed the development environment through an unmodified default administrator credential and a Grafana instance without single sign-on protection, subsequently gaining cluster administrator privileges via an unauthenticated MCP tool server and stealing credentials through an automated platform, ultimately accessing the production environment to read the customer database.This incident resulted in the exposure of customer account information, including organization names, account holder names, member email addresses, and password hashes. The attacker also had access to systems containing node credentials, although there is no evidence that they were read; however, Chainstack still urged customers to rotate their node credentials. Chainstack stated that customer-facing services operated normally during the incident, and customer nodes, consoles, and APIs were not modified. Investigations revealed that the attacker used the open-source framework ARTEX, with no evidence found of exploiting software vulnerabilities. Chainstack has cut off the attack access path and requested customers to change passwords, rotate node credentials, regenerate platform API keys, and remain vigilant against phishing information.

Minnesota Republican Congressman Tom Emmer was elected House Republican Whip after the midterm elections, securing the second-highest leadership position in the party. According to Politico, he defeated Texas Congressman August Pfluger in a closed-door vote of 103 to 76. Emmer previously served as the House Republican Majority Whip and will continue to be the number two in the party under the incoming Minority Leader Jim Jordan. The Democrats will take control of Congress in January next year.As Whip, Emmer will be responsible for rallying Republican votes, coordinating the party's legislative strategy, and maintaining party unity on key bills. Emmer has been a leading voice for the Republican Party on congressional digital asset issues. In March 2025, he announced the formation of a bipartisan Congressional Crypto Caucus with Congressman Ritchie Torres, aimed at garnering support for legislation on digital assets such as stablecoins and market structure.He is also the original co-sponsor of the CLARITY Act and introduced the Blockchain Regulatory Certainty Act, which aims to clarify that blockchain developers and infrastructure providers who do not control customer funds are not considered money transmitters under federal law. Republican Senator Cynthia Lummis stated on X that Tom is one of the most steadfast advocates for digital assets in Congress, leading the fight against government-controlled CBDCs and speaking out for American innovators.
