Help me Decrypt .RIGD Files.


Recommended Posts

I have used Emisisoft to scan an infection and I got the following message.

-------------------

Error: No key for New Variant online ID: A3oR4B4ov5QFfeOhQp0CE68ptUWPZz0GYC27eFFA

Notice: this ID appears to be an online ID, decryption is impossible

-------------------

What tool do you have to recover these files?

Hello @Inno Sci,

 

Welcome to the Emsisoft Support Forums.

 

I understand it is frustrating, but currently, we cannot decrypt files with an Offline-ID that we do not have the Private Encryption Key in our Database.

 

Please read this Topic. It contains information about your situation and whether or not your files can be decrypted.

我還 使用 Emisisoft 掃描感染並收到以下消息。

新變體在線 ID 沒有密鑰:2yeOe3cKPZytUBwStVQDmMb101WGTYdRZlWqlyn

注意:這個ID似乎是一個在線ID。解密是不可能的

 

我怎樣才能 恢復這些文件?

Yes, it is probably true. The Emsisoft Decryptor defines this fact very accurately. 

What to do? Everything is lost?
No. It is recommended that you save the encrypted files to an external drive. It is possible that in the future the decryption method will change or the extortionists will publish the decryption keys. There have been several such unexpected cases recently when others extortionists shut down their ransomware projects and published decryption keys and master keys for everyone who got encrypted. The percentage of such happy cases is small, but it still exists. 

Next, I'll tell you what you need to do now, immediately, and what you can try after that.

Why did this happen?

This 'STOP Ransomware' enters the PC due to the fact that computer is poorly protected. People often use free antivirus programs with the 'Free' label in the name. None of these programs will protect PC from programs similar to 'STOP Ransomware', because basic protection is not capable of this feat.
If users used comprehensive protection of the 'Internet Security' class, then it would help protect PC from ransomware attacks.

There is no 100% protection against malware, but what the 'Free' antivirus gives is 1-2 percent protection. 

After this attack, PCs could have stayed other malware elements. This maybe is an info-stealer and something else. Therefore, it is urgent to conduct a full check and destroy malware.

Use an comprehensive anti-virus software such as Emsisoft Anti-Malware to effectively remove the malware. 
You can get a free trial 30-days version of Emsisoft Anti-Malware here: https://www.emsisoft.com/en/home/antimalware/

It will help you clean your PC from other malware for free.

!!! You need to neutralize all malicious files in the system. This should be done as quickly as possible. Otherwise, the files may be encrypted using the online ID and decryption will never be possible.

Only after neutralizing all malicious files ...

I recommend this following method only when there is no other way... 

This is not the decryption, it is the recovery of certain types of files using the features of these files.

1) If you have encrypted ZIP/RAR archives, you can partially recover them. Only 1-2 files are damaged there. Remove the extension that the ransomware added to the archives, and extract the files in the usual way. Everything except 1-2 files will be fixed. If there is only 1 file in the archive, then it will most likely be unrecoverable.

2) There is an alternative (additional) way to recover some media files:
WAV, MP3, MP4, M4V, MOV, 3GP.

But before trying the alternative variant with media files, it is recommended that you make a copy of the encrypted files. Something will be restored better, something will be restored worse. 

Some types of files can be opened (restored) using the application in which they were created. To do this, you must first remove the extension added by the ransomware. Then can try to open the file from the program in which it was created. If you open audio and video files in the editor, it will restore the structure, and upon closing it will offer to save the changes in the file.

3) If you have PDFs or files of other e-books, then they may suffer in part if they were not protected from manual modification. Therefore, after removing the added extension, they can be partially read (~ 80%).

Unfortunately, it is not yet possible to recover files created in MS Office applications due to their sensitivity to any damage. They can be easily damaged without encryption. It is easier to recover and read text written on paper or on the stone than one created in MS Office.

An alternative method for other files has not yet been found.
