Ransom Note

Your network has been breached and all data were encrypted. Personal data, financial reports and important documents are ready to disclose. To decrypt all the data and to prevent exfiltrated files to be disclosed at you will need to purchase our decryption software. Please contact our sales department at: Login: Password: To get an access to .onion websites download and install Tor Browser at: https://www.torproject.org/ (Tor Browser is not related to us) Follow the guidelines below to avoid losing your data: - Do not modify, rename or delete *.key.2o4xo files. Your data will be undecryptable. - Do not modify or rename encrypted files. You will lose them. - Do not report to the Police, FBI, etc. They don't care about your business. They simply won't allow you to pay. As a result you will lose everything. - Do not hire a recovery company. They can't decrypt without the key. They also don't care about your business. They believe that they are good negotiators, but it is not. They usually fail. So speak for yourself. - Do not reject to purchase. Exfiltrated files will be publicly disclosed.
