Abstract
A system for suspending a computing device suspected of being infected by a malicious code is configured to receive a signal to initiate a suspension procedure of the computing device. The system captures states of instructions that are being executed by a processor of the computing device, where the instructions comprise the malicious code. The system prioritizes the operation of a kill switch button over the instructions being executed by the processor. The system sends notification signals to servers managing a user account associated with a user currently logged in at the computing device, indicating that the computing device is suspected of having been infected by the malicious code. In response to sending the notification signals to the servers, the user account is suspended. The system terminates network connections of the computing device such that the computing device is disconnected from other devices.
