What is Paradise ransomware? And how does it execute its attack?
Paradise ransomware appears to be a Ransomware as a Service or a RaaS. Ransomware as a Service is where a ransomware developer creates a ransomware and manages its development as well as operates the Command and Control server in exchange for some small ransom payments it obtains from its victims. Although Paradise ransomware’s activity is still low, the fact that it is distributed as RaaS is a clear sign that other less experienced crooks might pick up its code and further boost its distribution.
As of now it isn’t determined how Paradise ransomware infects computer but based on the entries in the event log of an infected computer, researchers concluded that it may be through Remote Desktop services. Once executed, the ransomware relaunches itself to obtain administrator privileges and then generate RSA 1024 key which is used to encrypt various files in the compromised computer. During the encryption, it appends the .paradise extension to each file along with the email address. Since Paradise uses RSA encryption, the encryption process is very slow. This is the ideal time for victims to hopefully detect the ongoing encryption and put a stop to it. After that, it drops its ransom note contained in a text file named #Decrypt My Files.txt with a brief description about Paradise ransomware. Here’s the full context of the ransom note:
Your important files produced on this computer have been encrypted due a security problem
If you want to restore them, write us to the e-mail: [email protected]
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us.
After payment we will send you the decryption tool that will decrypt all your files.
[FREE DECRYPTION AS GUARANTEE]
Before paying you can send to us up to 3 files for free decryption.
Please note that files must NOT contain valuable information
and their total size must be less than 1Mb
[HOW TO OBTAIN BITCOINS]
The easiest way to buy bitcoin is LocalBitcoins site.
You have to register, click Buy bitcoins and select the seller by payment method and price
Do not rename encrypted files
Do not try to decrypt your data using third party software, it may cause permanent data loss
If you not write on e-mail in 36 hours – your key has been deleted and you cant decrypt your files”
Its ransom note does not specify any amount for the ransom but only urges its victims to contact the perpetrators and pay as soon as possible giving its victims at least 36 hours. Regardless of how pressured you are, do not ever try to contact these crooks or even pay the ransom. This won’t actually get you nowhere for there is no guarantee that they will give you the encryption key once they get what they want. You can try out alternative ways to recover your files but before that, make sure that you eliminate the ransomware from your computer first.
How Paradise distribute its malicious files?
Usually, ransomware infections like Paradise distribute its malicious files using spam emails which are often disguised in the form of receipts, invoices, etc. Aside from that it also makes use of RDP attacks to infiltrate your computer which is why you must always keep your antivirus program and your computer system updated to prevent attacks like this.
