Ransom Note
Your network has been penetrated. All files on each host in the network have been encrypted with a strong algorithm. Backups were either encrypted or deleted or backup disks were formatted. Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover. We exclusively have decryption software for your situation No decryption software is available in the public. DO NOT RESET OR SHUTDOWN – files may be damaged. DO NOT RENAME OR MOVE the encrypted and readme files. DO NOT DELETE readme files. This may lead to the impossibility of recovery of the certain files. Photorec, RannohDecryptor etc. repair tools are useless and can destroy your files irreversibly. If you want to restore your files write to emails (contacts are at the bottom of the sheet) and attach 2-3 encrypted files (Less than 5 Mb each, non-archived and your files should not contain valuable information (Databases, backups, large excel sheets, etc.)). You will receive decrypted samples and our conditions how to get the decoder. Attention!!! Your warranty - decrypted samples. Do not rename encrypted files. Do not try to decrypt your data using third party software. We don`t need your files and your information. But after 2 weeks all your files and keys will be deleted automatically. Contact emails: [email protected] or [email protected] The final price depends on how fast you write to us. Clop
