BitKangoroo deletes files every 60 minutes but , A decryptor is already available

This particular ransomware is developed by a real scumbag who intends to delete a victims files if they do not pay fast enough.

This ransomware will encrypt a victim's files using AES-256 encryption and append the .bitkangoroo extension to encrypted files. It will then display a 60 minute countdown that when reached will cause the ransomware to delete one encrypted file. Once it deletes a file, it will reset the timer back to 60 minutes


Most importantly, this ransomware can be decrypted for free using Michael Gillespie's BitKangarooDecrypter."
