An extortion group calling itself the Crimson Collective claims to have breached Red Hat's private GitHub repositories, stealing nearly 570GB of compressed data across 28,000 internal projects.
An extortion group calling itself the Crimson Collective claims to have breached Red Hat's private GitHub repositories, stealing nearly 570GB of compressed data across 28,000 internal projects.
This data allegedly includes approximately 800 Customer Engagement Reports (CERs), which can contain sensitive information about a customer's network and platforms.
A CER is a consulting document prepared for clients that often contains infrastructure details, configuration data, authentication tokens, and other information that could be abused to breach customer networks.
Red Hat confirmed that it suffered a security incident related to its consulting business, but would not verify any of the attacker's claims regarding the stolen GitHub repositories and customer CERs.
"Red Hat is aware of reports regarding a security incident related to our consulting business and we have initiated necessary remediation steps," Red Hat told BleepingComputer.
"The security and integrity of our systems and the data entrusted to us are our highest priority. At this time, we have no reason to believe the security issue impacts any of our other Red Hat services or products and are highly confident in the integrity of our software supply chain."
While Red Hat did not respond to any further questions about the breach, the hackers told BleepingComputer that the intrusion occurred approximately two weeks ago.
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 GitHub 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.
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
During the second day of Pwn2Own Berlin 2025, competitors earned $435,000 after exploiting zero-day bugs in multiple products, including Microsoft SharePoint, VMware ESXi, Oracle VirtualBox, Red Hat Enterprise Linux, and Mozilla Firefox.
The highlight was a successful attempt from Nguyen Hoang Thach of STARLabs SG against the VMware ESXi, which earned him $150,000 for an integer overflow exploit.
Dinh Ho Anh Khoa of Viettel Cyber Security was awarded $100,000 for hacking Microsoft SharePoint by leveraging an exploit chain combining an auth bypass and an insecure deserialization flaw.
Palo Alto Networks' Edouard Bochin and Tao Yan also demoed an out-of-bounds write zero-day in Mozilla Firefox, while Gerrard Tai of STAR Labs SG escalated privileges to root on Red Hat Enterprise Linux using a use-after-free bug, and Viettel Cyber Security used another out-of-bounds write for an Oracle VirtualBox guest-to-host escape.
In the AI category, Wiz Research security researchers used a use-after-free zero-day to exploit Redis and Qrious Secure chained four security flaws to hack Nvidia's Triton Inference Server.
On the first day, competitors were awarded $260,000 after successfully exploiting zero-day vulnerabilities in Windows 11, Red Hat Linux, and Oracle VirtualBox, reaching a total of $695,000 earned over the first two days of the contest after demonstrating 20 unique 0-days.
The Pwn2Own Berlin 2025 hacking competition focuses on enterprise technologies, introduces an AI category for the first time, and takes place during the OffensiveCon conference between May 15 and May 17.
