Ransom Note
-------------------------------------------- | What happened to your files? -------------------------------------------- We breached your corporate network and encrypted the data on your computers. The encrypted data includes documents, databases, photos and more - all were encrypted using a military grade encryption algorithms (AES-256 and RSA-2048). You cannot access those files right now. But dont worry! You can still get those files back and be up and running again in no time. --------------------------------------------- | How to contact us to get your files back? --------------------------------------------- The only way to restore your files is by purchasing a decryption tool loaded with a private key we created specifically for your network. Once run on an effected computer, the tool will decrypt all encrypted files - and you can resume day-to-day operations, preferably with better cyber security in mind. If you are interested in purchasing the decryption tool contact us at bapcocrypt@ctemplar.com ------------------------------------------------------- | How can you be certain we have the decryption tool? ------------------------------------------------------- In your mail to us attach up to 3 files (up to 3MB, no databases or spreadsheets). We will send them back to you decrypted.
