Microsoft Research has announced a cloud-based malware detection service called Project Freta. The service will detect rootkits, cryptominers, and previously undetected malware strains lurking in your Linux cloud VM images. The company says it aims to make it extremely difficult and economically unfeasible for highly skilled malware creators to produce stealthy, undetectable strands. The project is based on four sensing tenets, which require no program can detect a sensor is present before it installs itself in the environment, Hide from the sensor as long as the program is within the monitoring view of the sensor.
