Ransom Note
  • *-------=SymmiWare=-------* All your files was ciphered by Strong algorythm AES-128. Take your time, no one will be able to decrypt your files without our decryption service. To decrypt files, pay $ 0 in Bitcoins. If you do not have 0 bitcoins (everyone has it) then go to the site localbitcoins.com and there send to our wallet (which we do not have) and write to the mail [email protected] to get the key and the decoder. We advise you not to mess around because you still do not restore their hands. We've also encrypted all your drives, files on your hard drives and network drives. AES-128 is the Most reliable military-grade cryptographic algorithm. There's no way to hack it, not even with a supercomputer. The file cutter will start in 48 hours. Don't be stupid and ugly like Patrick. Any hacking attempts can fuck all of your data and the locker will turn them into pee-pee. Good luck. Goodbye. P.S I'm not spreading, and I can't. P.P.S. The best time to send a letter: after November 25 (while we register the mail), and the fact that we wrote about 48 hours - it was a joke. We do not count down the time until the system is removed. *-------=SymmiWare=-------*
