If you've been in cybersecurity long enough, you develop a reflex: dramatic claims usually aren't true. So when a tweet started circulating in early April 2026 alleging 10 petabytes of data had been stolen from China's National Supercomputing Center in Tianjin—including defense documents and missile research—my reaction was the same as most practitioners: prove it. This brings us to the crucial question: did it really happen?

With EDR (Extended Detection and Response) becoming more necessary and common, it begs the question of what tactics and techniques are evading these protections. ProCircular recently conducted a penetration test involving evasion methods that did just that by successfully bypassing EDR protections by leveraging lay-of-the-land tools and incident response techniques. Our objective was to achieve full domain compromise within the targeted network, demonstrating the vulnerabilities and potential weaknesses that need to be addressed for robust cybersecurity. A walkthrough of the attack can be examined below.
