What is a PARADISE file?
A PARADISE file is a file that has been encrypted by Paradise ransomware, which is malware distributed by cybercriminals. It contains a file, such as a .JPG, .DOCX, .XLSX, .MP4, or .MP3 file, that has been renamed and encrypted by the virus. PARADISE files can be decrypted for free using the Emsisoft Decryptor for Paradise utility.
In September 2017, BleepingComputer.com user gschuck reported that their client's computer had been infected by a new form of ransomware called Paradise. This ransomware uses RSA encryption to encrypt users' files, appends the .paradise extension to each affected file, and generates a file named #DECRYPTMYFILES#.txt or ---==$$$OPEN_ME_UP$$$==---.txt in each folder containing an affected file. The TXT files contain instructions a user is supposed to follow to pay a ransom and receive a key they can use to decrypt their files. (You should never pay a ransom to decrypt your files.)
However, users do not need to pay a ransom to decrypt most files encrypted by Paradise ransomware. In October 2019, anti-malware company Emsisoft developed a Paradise decryption tool any Windows user can use to decrypt Paradise-infected files for free. In addition to being able to decrypt files appended with the .paradise extension, Emsisoft Decryptor for Paradise can decrypt PARADISE files appended with the .2k19sys, .p3rf0rm4, .exploit, .immortal, .FC, and other extensions.
How did my computer get infected by Paradise?
Typically, Paradise is distributed via phishing emails that contain malicious .ZIP, .IQY, or other attachments. Opening these attachments executes a PowerShell command that installs Paradise on your computer.
While Paradise is now an old form of ransomware, it is still used regularly. For example, in early 2020, users reported a new spam campaign that used emails pretending to be free offers, order receipts, and software keys to distribute Paradise using IQY attachments.
How to open a PARADISE file
Because PARADISE files are encrypted with ransomware, they cannot be opened. However, you can decrypt PARADISE files to restore them to their original state.
To decrypt PARADISE files, download the free Emsisoft Decryptor for Paradise utility. Then, open the decryptor, select the directory you want to decrypt, and decrypt your files. Repeat this process until you have decrypted all your files.
FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
