# Hacker Claims 10-Petabyte Data Theft From China Supercomputer Center

_Thursday, April 9, 2026 at 12:04 AM EDT · Cybersecurity, Policy · Latest · Tier 1 — Major_

A hacker is claiming to have stolen approximately 10 petabytes of data from the Tianjin Supercomputer Center in what would be one of the largest data breaches in history if verified.

The stolen data allegedly includes defense-related materials, according to reports from WION and USA Herald. The Tianjin facility houses supercomputers that have been used for both civilian research and military applications, including hypersonic weapons development and nuclear simulations.

The hacker is reportedly attempting to sell the data on underground forums. The 10-petabyte volume represents an enormous cache that could contain years of research, technical specifications, and potentially sensitive operational information.

Chinese authorities have not confirmed the breach. The Tianjin Supercomputer Center operates several high-performance systems, including Tianhe series supercomputers that have ranked among the world's fastest.

The alleged heist highlights ongoing cybersecurity vulnerabilities at critical research institutions. Nation-state supercomputing facilities represent high-value targets for both criminal actors and intelligence services seeking technical secrets.

Verification of the breach claims remains pending. Independent security researchers have not yet confirmed the authenticity of the data samples allegedly offered for sale.
