Federal authorities announced Tuesday that they have erased Chinese malware from thousands of computers across the United States.

Law enforcement turns the PlugX malware’s own self-delete mechanism against it, nuking the China-linked trojan from thousands of US machines.

According to the FBI, it worked on deleting the malware from over 4,000 Windows-based computers, further regarding that PlugX is capable of taking over a computer to steal the files and share them with the right people over in China.
