A major cybersecurity scare has emerged after a hacker known as “FlamingChina” claimed responsibility for what could be one of the largest data breaches ever linked to China. The alleged target is the National Supercomputing Center in Tianjin, a powerful and highly important facility that supports government, scientific, and defense-related work.
The scale of the claim is difficult to imagine. The hacker says more than 10 petabytes of data were stolen. To make this easier to understand, one petabyte equals 1,000 terabytes. A typical high-end laptop usually stores about one terabyte. This means the stolen data could fill millions of laptops completely. Such a huge volume of information makes this incident extremely serious, even though full verification is still pending.
The claims first surfaced earlier this year when “FlamingChina” reportedly shared samples of the stolen data on Telegram. These samples quickly caught the attention of cybersecurity researchers, who began examining whether the data might be real.
What Was Allegedly Stolen?
According to the hacker’s claims, the stolen data includes highly sensitive and possibly classified information from China. The samples shared online are said to contain aerospace research files, military simulations, and even technical designs related to missiles. Some documents reportedly carry “secret” markings in Chinese, suggesting a high level of sensitivity.

Experts who reviewed parts of these samples said the material appears consistent with the type of work carried out at the National Supercomputing Center in Tianjin, China. This center is known for handling complex and large-scale computing tasks. These include artificial intelligence research, climate modeling, engineering simulations, and projects linked to national defense.
Because of the wide range of work done at such facilities, the data stored there is extremely valuable. If the claims turn out to be true, the exposure of such information could have serious implications. Defense-related data, in particular, could be of interest to multiple global players.
At the same time, it is important to note that the full dataset has not been independently verified. Only small portions of the alleged data have been examined so far. However, even these small samples have raised concerns due to the nature of the content.
How the Breach May Have Happened
Details shared by “FlamingChina” suggest that the breach may have started through a compromised VPN domain. A VPN, or Virtual Private Network, is a tool that allows users to securely connect to systems from remote locations. While VPNs are designed to improve security, they can become weak points if not properly managed.
Once access was gained, the hacker reportedly used a botnet to carry out the attack. A botnet is a network of computers that can be controlled remotely to perform tasks. In this case, it was allegedly used to slowly extract large amounts of data from the system.
Instead of transferring all the data at once, the attacker is said to have used a gradual approach. Small chunks of data were taken over several months. This method helps avoid detection because it does not create sudden spikes in network activity. Security systems often rely on detecting unusual patterns, and slow extraction can bypass such alerts.
Cybersecurity experts note that while this method is not highly advanced, it can still be very effective. If monitoring systems are weak or not properly configured, even simple techniques can lead to massive breaches.
Data Sale Claims and Global Concerns
Another worrying part of this incident is that the stolen data is reportedly being offered for sale. According to the claims, small samples of the dataset from China are priced at thousands of dollars. Full access to the entire dataset is said to cost significantly more, with payments being accepted in cryptocurrency.
This raises serious concerns about who might gain access to the information. If the data includes defense-related research or sensitive technical designs, it could be highly valuable. Experts point out that only a limited number of organizations have the capability to fully analyze such a large amount of data, but even partial access could be risky.

The incident has also brought attention to broader cybersecurity challenges in China. Even advanced technological systems, such as those used at the National Supercomputing Center in Tianjin, are not completely immune to attacks. Weak points like unsecured VPNs or insufficient monitoring can create opportunities for attackers.
So far, there has been no official confirmation from authorities regarding the breach. Independent verification of the complete dataset is still ongoing. However, the claims made by “FlamingChina,” along with the sample data shared online, have already triggered widespread concern about the safety of critical digital infrastructure and the growing risks in the world of cyber warfare.
