Dotmap ransomware is a malicious software that stealthily penetrates the PC system and encrypts files that stored on computer disks. While encrypting, it renames all encrypted photos, documents and music so that they have the .dotmap file extension.
Immediately after the launch, the .Dotmap 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:
