Emsisoft Decrypter for HydraCrypt and UmbreCrypt 是一款勒索軟體的解密程式，專門用來解密受 HydraCrypt 和 UmbreCrypt 這兩種勒索軟體所感染的檔案，它們類似於 CrypBoss 疑為它的變種。為了查明您系統的正確解密金鑰，解密程式將需要您的一些協助。尋找您系統上任何加密過的檔案，同一位置應有該檔的原始未加密版本。同時選擇未加密和加密的檔案後將其拖放到解密程式的可執行檔上，如下所示︰
解密程式將根據您所提供的兩個檔案來試圖找出您系統的加密金鑰。這可能相當耗時且可能需要長達數天。
這新的變種導致檔案結尾達 15 位元組永久損壞無法挽回。對於大多數檔案格式來說這不重要，因此它可以只透過開啟和儲存檔案來復原檔案。對於其他的檔案格式，您就不會這麼幸運了。

Emsisoft Decrypter for HydraCrypt and UmbreCrypt can decrypt files infected with these two ransomware’s, which are similar to CrypBoss. This new variant causes up to 15 bytes at the end of the file to be damaged irrecoverably. Most file formats this isn’t crucial so it can be recovered by just opening and saving the files. For other file formats, you won’t be so lucky. In order to determine the correct decryption key for your system, the decrypter will require some help from you. Look for any encrypted file on your system, where you have the original unencrypted version of the file as well. Select, drag and drop both the unencrypted and encrypted files at the same time onto the decrypter executable. The decrypter will try to determine the encryption key for your system based on the two files you provided. This can be rather time-consuming and can take up to several days.
