Please note that the SSCC has backups of all U:\, Z:\, X:\, and V:\ drive data, so while recovering from this would be a time-consuming operation, your network drive files would be restored to you. However, in many cases all your personal files, even the ones on your U:\ drive and shared files you have access to on your department or research project's X:\ or V:\ drive, will be permanently destroyed (as no one recommends paying the ransom to the malware writers, as this just leads to more malware). This means that a computer infected with ransomware will often still be able to boot up and run, because the malware was not able to encrypt critical Windows system files. They do not require administrator credentials, because they run in your regular user account and simply encrypt any files your user account can write to.They are very damaging, because they will prevent you from being able to read any files (via a process called encryption) that you have access to both on your computer and also network drives (like your U:\ drive, and the X:\ drive) unless you pay ransom to the malware writer.However, when ransomware came onto the scene, two key features about it were apparent: The SSCC has already prevented users from running as Administrators on managed computers for years, for this very reason.
