US dismantles 911 S5 botnet used for cyberattacks, arrests admin

The U.S. Justice Department and international partners dismantled the 911 S5 residential proxy botnet and arrested its administrator, YunHe Wang, after an operation that seized infrastructure, domains, and assets; the botnet had infected millions of Windows machines (over 19 million unique IPs) via malicious VPN apps and sold proxied access to criminals, enabling large-scale fraud, harassment, and other illicit activity that resulted in substantial financial losses.
