"They allegedly found authentication tokens, full database URIs, and other private information in Red Hat code and CERs, which they claimed to use to gain access to downstream customer infrastructure.

The hacking group also published a complete directory listing of the allegedly stolen GitLab repositories and a list of CERs from 2020 through 2025 on Telegram.

The directory listing of CERs include a wide range of sectors and well known organizations such as Bank of America, T-Mobile, AT&T, Fidelity, Kaiser, Mayo Clinic, Walmart, Costco, the U.S. Navy’s Naval Surface Warfare Center, Federal Aviation Administration, the House of Representatives, and many others.

If you have any information regarding this incident or any other undisclosed attacks, you can contact us confidentially via Signal at 646-961-3731 or at tips@bleepingcomputer.com.

The hackers stated that they attempted to contact Red Hat with an extortion demand but received no response other than a templated reply instructing them to submit a vulnerability report to their security team.

According to them, the created ticket was repeatedly assigned to additional people, including Red Hat's legal and security staff members.

BleepingComputer sent Red Hat additional questions, and we will update this story if we receive more information.

The same group also claimed responsibility for briefly defacing Nintendo’s topic page last week to include contact information and links to their Telegram channel

Update 10/2/25: Story updated with correction from Red Hat that it was a GitLab instance that was breached and not a GitHub account."

A hacking group claims to have pulled data from a GitLab instance connected to Red Hat's consulting business, scooping up 570 GB of compressed data from 28,000 customers. From a report:The hack was first reported by BleepingComputer and has been confirmed by Red Hat itself. "Red Hat is aware of reports regarding a security incident related to our consulting business and we have initiated necessary remediation steps," Stephanie Wonderlick, Red Hat's VP of communications told 404 Media.

A file released by the hackers and viewed by 404 Media suggested that the hacking group may have acquired some data related to about 800 clients, including Vodafone, T-Mobile, the US Navy's Naval Surface Warfare Center, the Federal Aviation Administration, Bank of America, AT&T, the U.S. House of Representatives, and Walmart."
