By giving visibility to the microphone as much as the camera, it's easy to spot a program accessing the microphone that shouldn't be and block it. Keep Track of Eavesdropping with OverSightįor MacOS users wanting to monitor whether any programs are accessing their webcam or microphone, OverSight allows you to supervise these devices and alert you to any violations of your privacy. Once RansomWhere detects a program encrypting more than three files rapidly, your decision as to whether or not to let it continue is saved to a whitelist, further reducing false positives. While sometimes legitimate updates of apps like Adobe products may trigger this, smart math in the background is able to keep false negatives low by being able to discern between file encryption and compression. In a scenario where a malicious program was trying to encrypt your hard drive, you'd be warned early in the process and asked if you'd like to kill the program. Upon detection, the RansomWhere program halts the process that's encrypting and displays an alert to let you decide whether or not to let it proceed.
