Here’s everything you need to know about this ransomware, how to remove .Mogera ransomware and how to restore (decrypt) encrypted documents, photos and music for free.
Immediately after the launch, the .Mogera ransomware scans all available drives, including network and cloud storage, to determine which files will be encrypted. The ransomware uses the file name extension, as a way to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
