GlobeImposter is a Globe copycat that imitates the ransom notes and file extension found in the Globe ransomware kit. Encrypted files have the extension *.crypt and the base name of the file is unchanged. The ransom note is named "HOW_OPEN_FILES.hta" and can be found in all folders that contain encrypted files.
To start the decryption process you will need a file pair consisting of an encrypted file and the non-encrypted version of the same file. Select both and drag and drop them onto the decrypter binary to start the process.
