Ransom Note
::: Greetings ::: Little FAQ: .1. Q: Whats Happen? A: Your files have been encrypted and now have the "pecunia" extension. The file structure was not damaged, we did everything possible so that this could not happen. .2. Q: How to recover files? A: If you wish to decrypt your files you will need to pay in bitcoins. .3. Q: What about guarantees? A: Its just a business. We absolutely do not care about you and your deals, except getting benefits. If we do not do our work and liabilities - nobody will cooperate with us. Its not in our interests. To check the ability of returning files, you can send to us any 2 files with SIMPLE extensions(jpg,xls,doc, etc... not databases!) and low sizes(max 1 mb), we will decrypt them and send back to you. That is our guarantee. .4. Q: How to contact with you? A: You can write us to our mailbox: pecunia0318@airmail.cc or pecunia0318@goat.si or pecunia0318@tutanota.com .5. Q: How will the decryption process proceed after payment? A: After payment we will send to you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files. .6. Q: If I don�t want to pay bad people like you? A: If you will not cooperate with our service - for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice - time is much more valuable than money. :::BEWARE::: DON'T try to change encrypted files by yourself! If you will try to use any third party software for restoring your data or antivirus solutions - please make a backup for all encrypted files! Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.
