In a recent global law enforcement operation, authorities dismantled a colossal botnet that had been operating for nearly a decade. The U.S. Justice Department has accused YunHe Wang, a 35-year-old from the People’s Republic of China, of creating and spreading malware that infected millions of Windows computers worldwide. This malware formed a vast botnet known as 911 S5. Wang allegedly sold access to the compromised IP addresses to other cybercriminals, amassing millions of dollars.
