I do not need money, I receive payments from many companies every day and I deal with the encryption of many companies every day. More important than money is time for me. For this reason, I have time to inflate the number and bargain like other friends who do this business. The offer I have made for your company is very reasonable and not a big deal for you. If you do not pay, the data of the company that we have backed up after 7 days will be shared publicly on the internet and you will not be able to recover any of your encrypted data.
